Cluster headache: understandings of current knowledge and directions for whole process management.

Cluster headache (CH) is a common primary headache that severely impacts patients' quality of life, characterized by recurrent, severe, unilateral headaches often centered around the eyes, temples, or forehead. Distinguishing CH from other headache disorders is challenging, and its pathogenesis remains unclear. Notably, patients with CH often experience high levels of depression and suicidal tendencies, necessitating increased clinical attention. This comprehensive assessment combines various reports and the latest scientific literature to evaluate the current state of CH research. It covers epidemiology, population characteristics, predisposing factors, and treatment strategies. Additionally, we provide strategic insights into the holistic management of CH, which involves continuous, individualized care throughout the prevention, treatment, and rehabilitation stages. Recent advances in the field have revealed new insights into the pathophysiology of CH. While these findings are still evolving, they offer a more detailed understanding of the neurobiological mechanisms underlying this disorder. This growing body of knowledge, alongside ongoing research efforts, promises to lead to the development of more targeted and effective treatments in the future.

Hypertension as an Underlying Cause of Headache or Dizziness and the Usefulness of Choto-San for Both Diagnostic and Therapeutic Purposes.

Background Though headache, head discomfort, and dizziness are major complaints in neurosurgical outpatient departments in Japan, these nonspecific complaints are sometimes troublesome to treat, and most symptomatic treatments are not always sufficient to resolve patients' complaints. Objective This retrospective study was conducted to identify potential hypertension underlying symptoms relating to the head by prescribing choto-san, because patients with such symptoms were found to have relatively high blood pressure, and we realized that Kampo medicine was potentially effective for resolving the patients' conditions. Methods A total of 171 patients making their first visit to the neurosurgical outpatient division of our institution from January 2020 to June 2022 were investigated retrospectively. Symptoms were classified into three categories: headache, head discomfort, and dizziness. The effectiveness of choto-san, the rate of potential hypertension, and whether improvement in symptoms had a strong relationship with the prescription of choto-san were investigated. Results Choto-san significantly improved outcomes, with an odds ratio of 3.13 (95% confidence interval 1.83-5.35, p<0.001) for choto-san and 5.50 (95% confidence interval 1.24-24.4, p=0.025) for antihypertensives. The rate of choto-san prescription was significantly higher in patients who were diagnosed with hypertension (test of independence p<0.001). Choto-san was thought to be the most effective for the aforesaid symptoms with accompanying potential hypertension. Conclusion Hypertension was shown to be one of the main causes of various nonspecific complaints. Choto-san was an effective medicine not only for improving patients' subjective symptoms but also for identifying potential hypertension, which may lead to the prevention of cerebrovascular diseases.

Transverse Sinus Stenosis as an Underdiagnosed Cause of Chronic Headache: A Case Report.

Transverse sinus stenosis (TSS) is an abnormality in the cerebral venous system in which the narrowing of the transverse sinus of the brain leads to obstructed cerebral venous outflow. It is an infrequent, incidental radiological finding. However, it is not uncommon among patients with chronic headaches of unclear cause, particularly those that remain unexplained after initial evaluation or those that are refractory to medical treatment. Its diagnosis frequently eludes the initial workup, and a high degree of suspicion should be maintained since its identification can lead to potentially curative treatment. This report describes the case of a 36-year-old female with a history of chronic headache who was found to have TSS. This paper discusses its etiology, pathophysiology, clinical presentation, radiological findings, and management.

Dry Needling Techniques as a Treatment for Improving Disability and Pain in Patients with Different Types of Headache: A Systematic Review and Meta-analysis.

BACKGROUND: Headaches, a widespread neuromuscular ailment, pose a significant burden on individuals and society, necessitating both pharmacological and non-pharmacological interventions. Dry needling (DN) has surfaced as a notable non-pharmacological alternative for addressing headaches. We aim to compare DN intervention with the control group in the management of different types of headaches. METHODS: A comprehensive meta-analysis was conducted, encompassing a systematic exploration of five electronic databases up to May 2023, with studies assessed for validity using the Cochrane risk of bias tool. Eligible studies included those with a control group, which could consist of sham interventions, physiotherapy, or pharmacological treatments. Outcomes related to disability, headache intensity, and frequency were extracted and analyzed. RESULTS: Out of 4304 studies screened, 13 randomized controlled trials (RCTs) were included in this systematic review, of them 10 RCTs were included in the meta-analysis. A significant decline in the disability score and headache intensity was evident in the DN group compared to the control group, one and three-month follow-ups. Specifically, substantial reductions in headache frequency were prominent after one and three months post-intervention. CONCLUSION: Dry needling manifests as a potent intervention, diminishing headache intensity and frequency, albeit with lower impact on disability scores. The observed benefits were especially pronounced after one and three months, though the heterogeneous nature of some data analyses mandates further detailed studies to gain a clearer understanding of DN's efficacy on the assessed outcomes.

Addressing the barrier of transport costs in accessing headache care in Sub-Saharan Africa.

The article by Leone et al. (2024) highlights the significant barrier of transport costs in accessing headache care for HIV-positive patients in Malawi, a concern that resonates with challenges observed in opioid agonist therapy (OAT) in Taiwan. This letter draws parallels between the findings of Leone et al. and the Taiwanese experience, where distance to treatment centers has been shown to influence patients' choice of OAT. The discussion underscores the importance of expanding healthcare service availability and exploring telemedicine as potential solutions to mitigate geographical barriers. Integrating these approaches could improve patient retention and treatment outcomes in both regions. This commentary emphasizes the broader implications of transport-related barriers in healthcare access, advocating for strategic interventions to enhance healthcare delivery in resource-limited settings.

Smoking and cluster headache presentation and responsiveness to treatment.

BACKGROUND: Though an association between cluster headache (CH) and smoking has been postulated, data from the Middle East region is scarce. AIM OF WORK: To study the relationship between smoking and CH clinical characteristics and responsiveness to therapy in Egypt. METHODOLOGY: This was a prospective cohort hospital-based study conducted on patients with episodic and chronic CH in a tertiary headache clinic in Egypt during the period between 2019 and 2023. Patients were consecutively recruited at the time of their presentation and were followed up for two weeks after initiation of prophylactic treatment and steroids (as transitional therapy). RESULTS: Of 172 patients with CH recruited, 144 (83.7%) were smokers. Twenty-eight patients (16.3%) had chronic CH. The mean age was 42.08 ± 10.93 (20-66) years, and 131 (76.2%) were males. Smokers had a significantly higher median number of cluster bouts in the past five years (3.0 (IQR2.0-4.0) versus 2.0 (IQR 1.0-2.0)) and worse HIT-6 scores [51.0 (44.0-59.75) versus 41.0 (38.0-41.75)] than non-smokers (p < 0.001). The number of cluster bouts in the past five years was positively correlated with the smoking index (r = 0.249 (p = 0.006) and the smoking duration (in years) (r = 0.392 (p < 0.001)). HIT-6 scores were significantly correlated with the age at smoking onset (r=-0.190, = 0.023), smoking index (r = 0.519, p < 0.001), smoking duration (r = 0.611, p < 0.001), and number of cigarettes consumed per day (r = 0.392, p < 0.001). CONCLUSION: Smoking is significantly correlated with the daily frequency of CH attacks, the frequency of CH bouts in the past five years, and the HIT-6 scores among our cohort.

Atypical Presentation of Sphenoid Sinusitis With Prevertebral Involvement.

Isolated sphenoid sinusitis (ISS) is a rare but potentially serious condition, often leading to severe complications due to delayed diagnosis and treatment. This case report discusses a 75-year-old male with type 2 diabetes mellitus who presented with severe left-sided headache and neck pain. Diagnostic imaging revealed isolated sphenoid sinusitis with prevertebral extension, a rare occurrence that highlights the potential for deep neck space involvement. The patient underwent endoscopic transnasal incision and drainage of the prevertebral abscess with a left sphenoidotomy, resulting in full recovery without recurrence. This case emphasizes the importance of prompt recognition and intervention in ISS, particularly in cases with atypical presentations. The report also discusses the complex anatomy of the sphenoid sinus and its surrounding structures, the broad differential diagnosis of sphenoid sinus opacification, and the necessity for a multidisciplinary approach to management. This case contributes to the limited literature on ISS with prevertebral extension and underscores the critical need for early diagnosis and aggressive treatment to prevent severe complications.

Etiology and characteristics of non-aneurysmal thunderclap headache presenting to an acute setting.

OBJECTIVES: To describe the characteristics and causes of non-aneurysmal thunderclap headache (TCH) and compare serious from benign underlying causes. METHODS: Retrospective cohort study of consecutive adult patients with TCH presenting to a tertiary care academic medical center between 2010 and 2020. Aneurysmal subarachnoid hemorrhage cases were excluded. Cases were categorized into serious or benign; serious TCH was defined as any condition in which delayed diagnosis and treatment could result in neurological disability or death. Risk factors for serious TCH were analyzed. We adhere to standardized guidelines for reporting observational studies. RESULTS: A total of 932 patients presented with TCH. After exclusion of 393 patients with aneurysmal-type subarachnoid hemorrhage, 539 were included in the analysis. One-half (n = 275, 51.0 %) had a serious cause. Median age was 51 years, 69.0 % were female. Most frequent diagnoses were intracranial hemorrhage (n = 102, 18.9 %), reversible cerebral vasoconstriction syndrome (n = 97, 18.0 %), and idiopathic TCH (n = 102, 38.6 %). A multivariable logistic regression model for prediction of serious TCH included age, hypertension, migraines, recurrent TCH, level of consciousness and other clinical exam findings, and achieved an AUROC of 0.732. This score had a sensitivity of 79.9 % (95 % CI 73.5-83.5 %) for the identification of serious TCH. A 0.5-point increase in the risk score was associated with a 73 % increase in the odds of serious TCH (odds ratio 1.73, 95 % CI 1.53-1.95, p < 0.001). CONCLUSION: Our study describes the relative frequency of presentation and etiologies among patients with TCH This score can aide clinicians in recognising patients with potentially serious cause of TCH, for whom additional imaging and neurological consultation is necessary.

Treatment of migraine with aura with osteopathic manipulative treatment: a case report with renewed perspectives.

Migraines make up a significant number of office visits every year, yet their pathophysiology and etiology remain largely elusive. This case report presents a 33-year-old patient who originally presented to the emergency department (ED) as a stroke alert and was later determined to have migraine with aura. The patient experienced an acute onset of headache, dizziness, and new-onset expressive aphasia. Before administration of a migraine cocktail, osteopathic manipulative treatment (OMT) was performed and was able to fully resolve all of her symptoms. In an effort to explain the outcomes in this case, a review of the current literature was performed, which provides an interesting perspective on the interplay of the musculoskeletal system and neuroanatomy. The literature establishes that somatic dysfunctions in the cervical vertebrae and trapezius may play a role in migraines and provide rationale for the use of OMT.

Clinical Findings, Radiological Characteristics, and Treatment Options of Spontaneous and Secondary Intracranial Hypotension: A Single-Center Experience in Turkey.

Introduction  Intracranial hypotension can occur for many reasons, including trauma, surgery, congenital defects, or spontaneous rupture of the dura mater. Symptoms appear long before cerebrospinal fluid (CSF) leaks are diagnosed. Treatment procedures include a variety of conservative and invasive techniques appropriate to the nature of the etiological cause and the severity of the disease. In this cross-sectional study, we aimed to investigate the clinical and imaging features and treatment options of intracranial hypotension patients and to compare them in terms of different etiologies. Methods The data from intracranial hypotension patients were analyzed retrospectively. Symptomatology, neurological findings, and radiological features were compared between patients with spontaneous intracranial hypotension (SIH) and those with secondary causes. Radiological outcomes of conservative treatment and epidural blood patch (EBP) were also evaluated for both groups. Results Of the 30 patients, 23 were female. In 14 of the patients (46.6%), a possible cause of CSF leakage was detected. Compared to intracranial hypotension patients with a secondary cause, SIH patients complained of posterior neck and shoulder pain more frequently (p=0.014, p=0.006). MRI features did not differ significantly when the two groups were compared (p>0.05). The first and sixth-month follow-up MRIs of patients treated with EBP or a conservative approach showed similar improvement rates (p=0.788). Conclusions There was no significant difference in radiological recovery time between conservative treatment and EBP in patients with intracranial hypotension. Radiological recovery times are similar in patients with secondary intracranial hypotension and SIH.

The burden of headache disorders in the adult population of Mongolia: estimates, and a health-care needs assessment, from a cross-sectional population-based study.

BACKGROUND: Having previously shown headache disorders to be prevalent in Mongolia, here we elaborate on headache as a public-health concern in this country, reporting symptom burden and headache-attributed impaired participation at individual and societal levels, and conducting a health-care needs assessment. METHODS: The study followed the standardized methodology developed by the Global Campaign against Headache, generating a representative general-population sample through multi-level randomized cluster sampling. Participants aged 18-65 years were interviewed at unannounced household visits by interviewers administering the HARDSHIP questionnaire. Symptom burden was established through questions on frequency, duration and intensity of headache, with proportion of time in ictal state calculated from frequency and duration. Individual impaired participation was established through the HALT questionnaire, enquiring into lost time from paid and household work and from leisure activities. Symptom burden and impaired participation yesterday were also assessed in those reporting headache yesterday. Population-level estimates were derived by factoring in prevalence. RESULTS: The total sample included 2,043 participants. Those reporting any headache in the last year (n = 1,351) spent, on average, 9.7% of all their time with headache, losing 1.3 workdays and 2.4 household days/3 months. These losses were considerably higher among those with probable medication-overuse headache (37.5%, 3.5 workdays, 6.7 household days) or other headache on ≥ 15 days/month (H15+) (21.9%, 2.4 workdays, 5.1 household days). At population-level (including those with and without headache), 6.2-7.4% of all time was spent with headache, 3.1% with H15+; 0.8 workdays and 1.4 household days/person/3 months were lost to headache, 0.3 workdays and 0.6 household days to migraine (the biggest contributor of all headache types). Our needs assessment estimated that one third (33.2%) of the adult population of Mongolia have headache (mostly migraine or H15+) likely to benefit from health care. CONCLUSION: This first population-based study on headache burden in Mongolia shows high levels of individual and societal burden, with H15 + the cause of greater burden at population level than migraine and TTH combined. Migraine, however, has the biggest impact on the nation's productivity. From a purely economic perspective, Mongolia, with limited health resources, would probably be best served by focusing on mitigating migraine-attributed burden.

The association between dietary antioxidant quality score and intensity and frequency of migraine headaches among women: a cross-sectional study.

BACKGROUND: Migraine is an episodic disorder and a frequent form of headache. An impaired balance between free radical production and an impaired antioxidant defense system leading to oxidative damage may play a major role in migraine etiology. We sought to investigate whether dietary antioxidant quality score (DAQS) is associated with migraine intensity and frequency among women suffering from migraine. METHODS: This cross-sectional study was conducted on 265 women. The data related to anthropometric measures and dietary intake were collected. DAQS score was calculated based on FFQ (food frequency questionnaire) vs. the reference daily intake (RDI) quantity. To measure migraine intensity, the migraine disability assessment questionnaire (MIDAS) and visual analog scale (VAS) were used. The frequency of headaches was defined as the days the participants had headaches in the last month and a 30-day headache diary was used. RESULTS: The results of the study demonstrated that VAS, MIDAS, and frequency of headaches were reduced significantly from the low DAQS (poor quality of antioxidants) to high DAQS (high quality of antioxidants) after adjusting covariates. Also, multinomial regression showed there was an inverse association between higher DAQS and the frequency of headaches. In the adjusted model, subjects with the higher DAQS were 69% less likely to have moderate migraine disability, compared with those with the lower DAQS. Linear regression showed, there was an inverse association between vitamin C intake and the grades of pain severity.َAlso in a crude model, a negative association was found between vitamin E and the frequency of headaches. CONCLUSION: In conclusion, Participants with higher DAQS had lower migraine intensity and headache frequency. In addition, the consumption of vitamin C may potentially associate with decreasing the severity of headaches. Dietary antioxidants should be monitored closely in individuals suffering from migraine.

Oral and dental health status in patients with chronic headache.

INTRODUCTION: Headache is an illness with high prevalence and adverse effects on quality of life. As oral or dental problems such as pain can trigger or aggravate it, we aimed to investigate and compare oral and dental health status in patients affected with chronic headaches and healthy individuals. METHODS: The present case-control study included 60 patients with chronic headaches (case) and 60 healthy individuals (control) in Rasht, Iran. The demographic characteristics and clinical examinations, including decayed/missing/filled teeth (DMF-T) and community periodontal index of treatment needs (CPITN) indices, as well as bruxism, frequency of tooth brushing and flossing, and maxillary and mandibular tooth wear were recorded in a checklist. Data analysis was performed using the IBM SPSS version 28 at a significance level of 0.05. RESULTS: The case group consisted of 25 men (41.7%) and 35 women (58.3%) with an average age of 32.55 ± 6.62 years, while the control group had 27 men (45%) and 33 women (55%) with an average age of 30.95 ± 6.33 years. The study groups were not significantly different in bruxism, frequency of tooth brushing and flossing, DMFT, CPTIN, and maxillary and mandibular tooth wear. CONCLUSION: It seems that chronic headaches do not significantly affect the oral and dental health of the sufferers. Moreover, it appears that these patients are well aware of the role of oral and dental hygiene in triggering or aggravating the episodes of headaches.

Evaluating the Frequency of Osmophobia in Tension-Type Headache: A Comparative Study on Migraine.

Introduction Osmophobia is hypersensitivity to certain odors. Although osmophobia is a symptom related to migraine, it is also reported in tension-type headache (TTH). Osmophobia is recommended for inclusion in the migraine diagnostic criteria because it increases sensitivity and shows absolute specificity. However, there is no evidence of the association between TTH and osmophobia. This study aimed to evaluate the prevalence and clinical characteristics of osmophobia in a cohort of migraine and TTH patients. Methods For the current analysis, patients who met the inclusion criteria among patients diagnosed with migraine and TTH according to the International Classification of Headache Disorders III criteria in the neurology outpatient clinics of Ankara City Hospital and Akyazi State Hospital were selected retrospectively. A total of 214 patients (129 with migraine and 85 with TTH) were included in the study. Patients' characteristics, visual analog scale (VAS) pain scores, and Migraine Disability Assessment Scale (MIDAS) scores were recorded. Osmophobia characteristics in migraine and TTH patients were compared along with clinical parameters between the groups and within the groups. Results Osmophobia was found in 68% of migraine patients. The most common type of smell that migraine patients experienced was the scent of perfume. A total of 31.3% of the patients with TTH had osmophobia. While the most irritating odorant in migraine patients was perfume (32%), in TTH patients, it was the smell of food (10.5%). There were no significant differences between osmophobia, and age, education level, disease duration, pain frequency, attack duration, or VAS score in both migraine patients and TTH patients. There was also no significant difference between migraine patients with (2.42) and without (2.33) osmophobia in terms of the MIDAS score. Discussion Our study indicates that osmophobia observed in migraine is valuable in differential diagnosis. However, it can be significantly identified in TTH patients. It should be used together with other supporting criteria in differential diagnosis. It would also be useful to question the characteristics of osmophobia in more detail in the anamnesis.

Causal relationship between primary headache mediated by circulating cytokines and cerebral cortex structure: a mediation Mendelian randomization study.

Inflammation may be related to structural changes in the cerebral cortex. We aimed to explore whether cytokines mediate the link between these changes and primary headache. The summary statistics of genome-wide association study (GWAS) related to migraine and its subtypes, cluster headache were derived from the FinnGen Release 10 database, and tension-type headache data was from the GWAS Catalog. Ninety-one cytokines were obtained from genome-wide pQTL mapping data. GWAS data on cortical surface area (SA) and thickness (TH) came from the ENIGMA Consortium. The methods of Mendelian randomization (MR) analysis included the inverse-variance-weighted (IVW), MR-Egger, and weighted median. Migraine reduces the SA of paracentral[ß = -1.3645, OR = 0.2555, 95%CI (0.0660, 0.9898)] by fibroblast growth factor-23(FGF-23), with an intermediate ratio (IR) of 38.13%. Migraine may reduce the TH of superior parietal[ß = -0.0029, OR = 0.9971, 95%CI (0.9943, 0.9999)] by interleukin (IL)-15RA, with an absolute IR of 11.11%. Migraine without aura may reduce the TH of rostral anterior cingulate[ß = -0.0005, OR = 0.9995, 95%CI (0.9991, 0.9999)] by IL-18R1, with an IR of 11.63%. FGF23 and IL-15RA are associated with reduced SA or TH in migraine, while IL-18R1 is associated with increased TH in migraine without aura.

Effectiveness of combining greater occipital nerve block and pulsed radiofrequency treatment in patients with chronic migraine: a double-blind, randomized controlled trial.

BACKGROUND: Pulsed radiofrequency (PRF) treatment targeting the greater occipital nerve (GON) has shown efficacy in treating various conditions. This double-blind, randomized controlled study aimed to evaluate the effects of combining PRF therapy with GON block (GONB) therapy in patients with chronic migraine. METHODS: The study consisted of two groups: GONB and GONB + PRF, each comprising 16 patients with chronic migraine. Using 0.5-Hz sensorial stimulation, a 5-cm-long radiofrequency needle was inserted under ultrasound guidance in both groups. Subsequently, all patients received a GONB by administering 2 mL of 0.25% bupivacaine. In the GONB + PRF group, patients underwent 4 min of PRF at 42℃, whereas the GONB group did not receive any PRF treatment. Follow-up examinations were performed at 1, 2, 3 and 6 months after the procedure to evaluate the frequency and severity of migraine attacks, number of headache days, and analgesic consumption. RESULTS: In the GONB + PRF group, the visual analog scale (VAS) score, number of migraine attacks, number of headache days, and analgesic consumption were significantly lower compared to the GONB group (P < 0.05). Significant decreases (60%) in mean VAS scores, number of migraine attacks, number of headache days, and consumption of analgesic medications were observed in the GONB + PRF group at the 1-, 2-, 3-, and 6-month follow-ups compared with the pre-treatment period (P < 0.05). CONCLUSIONS: The combination of GONB and PRF presents a promising new treatment option for patients with chronic migraine. This approach has demonstrated efficacy in minimizing analgesic use, decreasing the frequency of migraine attacks, reducing the number of headache days and decreasing the severity of migraine attacks. TRIAL REGISTRATION: NCT05464212.

Assessment of Public Awareness on Alarming Signs of Posttraumatic Intracranial Hemorrhage in the Jeddah Population: A Cross-Sectional Study.

Background Post-traumatic intracranial hemorrhage is a life-threatening condition, and early detection and response can significantly reduce morbidity and mortality rates. The aim of this study was to assess public awareness of the alarming signs of intracranial bleeding after trauma in adults in Jeddah, Saudi Arabia. Methodology From August 2023 to April 2024, a descriptive cross-sectional study was conducted using a five-scale structured questionnaire: demographics, risk factors for road traffic accidents, alarm signs and symptoms, ability to recognize these signs, and participants who experienced head trauma. The study focused on people aged 18 and over living in Jeddah. Results A total of 584 participants were included, with 34.2% males and 65.8% females. Findings revealed that 57% recognized the critical need for medical help after head trauma. Furthermore, only 45% of the population were unaware that low levels of awareness or wakefulness indicate bleeding, reflecting a low awareness level in the adult population. Among children, only 34% recognized changes in eating and lactation habits, and 54% identified continuous crying and irritability. Furthermore, 66% of participants identified loss or change in consciousness as a symptom that required hospital admission, while 60% recognized chronic headaches as a critical sign. Conclusion This study revealed the critical need for public health campaigns to improve awareness and understanding of signs of intracranial post-traumatic bleeding. The results highlighted the importance of early medical interventions to reduce the morbidity and mortality associated with this condition.

Computed Tomography Findings of Patients Presenting With Headache: 4-Year Retrospective Two-Center Study in Central and Western Regions of Ghana.

Objectives: The radiographic assessment of the head is a crucial part of headache care. A computed tomography (CT) scan enables a more detailed analysis of the condition and more focused care. This study examined head CT scans to determine what kinds of anomalies were present in patients with headaches as their primary complaint. Methods: We evaluated 4 years' worth of CT scan data from head exams conducted at two diagnostic facilities in Ghana's western and central regions. We examined data on 477 patients with a headache as their primary complaint between January 2017 and December 2020. We employed chi-square and Fisher's exact tests (where applicable) to compare head CT diagnoses between age groups, gender, headache subtypes, and brain lesion subgroups. Results: There were 53.5% (n = 255) females and 46.5% (n = 222) males in the study. The average age of patients was 38.67 ± 17.23 years, with an annual rate of abnormal CT diagnoses ranging from 35.9% in 2017 to 45.4% in 2022. Abnormal head CT diagnoses are strongly correlated with age groups and patient gender (p = 0.011 and p = 0.009, respectively). Of the 202 patients, 15.3% and 24.3% were classified as intracranial lesions and extracranial lesions, respectively. Maxillary sinusitis affected nearly 60% of the patients, while tumors and hemorrhages affected 25.2% and 11.9%, respectively. Conclusions: A CT scan of the head is essential to detect abnormalities in nearly 50% of patients suffering from various degrees of headache. Sinusitis, brain tumors, and hemorrhage were common lesions detected. It is crucial to create local standard operating procedures to promote better utilization of this type of imaging service, particularly among patients who have been diagnosed with headaches.

A case of MRI-induced headache caused by an intracranial foreign body.

This case report delves into a unique occurrence of MRI-induced headaches attributed to an unsuspected intracranial foreign body. A male patient, presenting persistent headaches, experienced exacerbation of pain upon entering the MRI suite, hindering the imaging procedure. A subsequent head CT scan revealed a nail within the cranial cavity, stemming from a previous nail gun injury. Surgical removal was deemed unsafe, leading to continued observation. This case emphasizes the need for cautious exploration of abnormal symptoms in the MRI suite, urging healthcare professionals to consider potential foreign bodies. The incident underscores the risk of metallic fragments causing complications during MRI procedures and highlights the importance of thorough patient assessment before resorting to MRI imaging.
