RESUMO
BACKGROUND: ETMR is a unique and highly malignant brain tumor mostly occurring in infants. This report provides a comprehensive overview of the clinical presentation, histological aspects, radiological features, and therapeutic options of ETMR. Being the first report on the co-occurrence of NF1 with ETMR, it highlight the challenges of managing a patient with complex medical conditions. CASE REPORT: We present a case of a 3 and 1/2-year-old girl with neurofibromatosis type 1 (NF1), later diagnosed with a supratentorial brain tumor reported as an embryonal tumor with multilayered rosettes (ETMR), along with possible co-occurrence of constitutional mismatch repair deficiency (CMMRD) on immunohistochemistry (IHC); however, germline testing was not performed. Even though NF1 can be associated with tumors such as gliomas, the literature has no previous case reports of ETMR coexisting with NF1. CONCLUSION: Exploring the link between NF1 and ETMR with CMMRD is crucial to improving and establishing more treatment protocols. Therefore, reporting each case's unique features would be essential in developing appropriate treatment protocols.

Introduction: Initiated in June 2019, this collaborative effort involved 15 public and private sector hospitals in Pakistan. The primary objective was to enhance the capacity for pediatric neuro-oncology (PNO) care, supported by a My Child Matters/Foundation S grant. Methods: We aimed to establish and operate Multidisciplinary Tumor Boards (MTBs) on a national scale, covering 76% of the population (185.7 million people). In response to the COVID-19 pandemic, MTBs transitioned to videoconferencing. Fifteen hospitals with essential infrastructure participated, holding monthly sessions addressing diagnostic and treatment challenges. Patient cases were anonymized for confidentiality. Educational initiatives, originally planned as in-person events, shifted to a virtual format, enabling continued implementation and collaboration despite pandemic constraints. Results: A total of 124 meetings were conducted, addressing 545 cases. To augment knowledge, awareness, and expertise, over 40 longitudinal lectures were organized for healthcare professionals engaged in PNO care. Additionally, two symposia with international collaborators and keynote speakers were also held to raise national awareness. The project achieved significant milestones, including the development of standardized national treatment protocols for low-grade glioma, medulloblastoma, and high-grade glioma. Further protocols are currently under development. Notably, Pakistan's first pediatric neuro-oncology fellowship program was launched, producing two graduates and increasing the number of trained pediatric neuro-oncologists in the country to three. Discussion: The initiative exemplifies the potential for capacity building in PNO within low-middle income countries. Success is attributed to intra-national twinning programs, emphasizing collaborative efforts. Efforts are underway to establish a national case registry for PNO, ensuring a comprehensive and organized approach to monitoring and managing cases. This collaborative initiative, supported by the My Child Matters/Foundation S grant, showcases the success of capacity building in pediatric neuro-oncology in low-middle income countries. The establishment of treatment protocols, fellowship programs, and regional tumor boards highlights the potential for sustainable improvements in PNO care.
RESUMO
Objectives: To identify that incidence of pulmonary barotrauma secondary to mechanical ventilation for the management of acute respiratory distress syndrome associated with coronavirus-disease-2019, and to compare it with the incidence of pulmonary barotrauma trauma secondary to mechanical ventilation associated with all the other causes. METHODS: The retrospective case-control study was conducted at the Aga Khan University Hospital, Karachi, and comprised data from October 2020 to March 2021 of patients who underwent mechanical ventilation. The data was divided into two groups. Data of acute respiratory distress syndrome associated with coronavirus-disease-2019 was in group 1, and that of acute respiratory distress syndrome associated with any other cause in control group 2. Medical records were reviewed to obtain demographic and clinical data, while the institutional picture archiving and communication system was used to review radiological images. Data was analysed using SPSS 24. RESULTS: Of the 261 cases, 115(44%) were in group 1; 87(75.6%) males and 28(24.3%) females. There were 146(56%) controls in group 2; 96(65.7%) males and 50(34.2%) females. There were 142(54.4%) subjects aged >60 years; 61(43%) in group 1 and 81(57%) in group 2. The incidence of pulmonary barotrauma in group 1 was 39(34%) and 8(5.5%) in group 2 (p<0.0001). CONCLUSIONS: Mechanical ventilation in the management of acute respiratory distress syndrome associated with coronavirusdisease- 2019 was found to be associated with a significantly higher incidence of pulmonary barotrauma than acute respiratory distress syndrome associated with any other cause.

INTRODUCTION: Craniopharyngioma constitutes approximately 10% of primary brain tumors in children. It can cause considerable morbidity and mortality due to the local aggressiveness of the tumor itself or its management affecting the hypothalamus-pituitary axis and optic pathway involvement. There is very scarce data available from LMIC which makes the management controversial where multidisciplinary teams are already not available in most of the centers. This is a single-center cross-sectional retrospective review of 20-year record of 49 patients with craniopharyngioma treated between 2001 and 2020 at Aga Khan University Hospital, a tertiary care center in Karachi, Pakistan. METHODS: We have assessed the epidemiological data of children presenting with the diagnosis of craniopharyngioma, treatment modalities used, and neurological, endocrine, and hypothalamic complications in these patients. The assessment involved a retrospective review of medical records and medical follow-up. RESULTS: Out of a total of 49 patients, 26 (53%) were male, and 23 (46.9%) were female. The mean age was 9.5 years (SD ± 4.5 years). Most common symptoms at initial presentation were headache 41 (83.6%), visual deficit 40 (81.6%), nausea and vomiting 26 (53%), and endocrine abnormalities 16 (32%). Treatment modalities used at our center include gross total resection 11 (22%) and subtotal resection 38 (77%) out of total, while 6 (12.2%) patients received intracystic interferon. Histopathologic findings of the majority of patients (40 (81%)) revealed an adamantinomatous type of tumor. Only 23 (46.9%) children followed in clinic post-op. Median follow-up after craniopharyngioma presentation was 5 years (± 2.1 SD, range: 2-10 years). Pituitary hormone deficiencies (98%) and visual disturbances (75%) were the most common long-term health conditions observed. CONCLUSIONS: Since pituitary hormone deficiencies and visual disturbance were the most common long-term health conditions observed in our study, these patients require a multidisciplinary team follow-up to improve their quality of life.

The purpose of this study was to assess the knowledge of the radiology personnel regarding contrast media used in radiology and the management of associated adverse drug reactions. Methods: A questionnaire-based cross-sectional study was conducted from 21 February to 31 March 2019 in five major hospitals of Peshawar, Pakistan. A 30-item questionnaire was adopted from the existing literature containing both open and closed-ended questions and the authors conducted a pilot study among 25 participants to assess the face validity of the tool. A universal sampling technique was adopted. Descriptive statistics were used to summarize the findings of the study. Results: Less than half of the participants could correctly classify iodinated contrast media used in radiology on the basis of ionicity and osmolaity. Sixty-three percent chose severe contrast material-induced allergic reaction as type I hypersensitivity reaction while almost half of them correctly identified the features of iodinated contrast media associated with lesser side effects. Very few of them (6.7%) had read the ACR 2018 manual on contrast media. Regarding the risk factors for acute adverse reactions and signs/symptoms of anaphylaxis few could answer satisfactorily. Twenty-eight percent of participants correctly identified epinephrine as the initial medication in an anaphylactic reaction. Regarding the preferred route of administration, concentration and dose of epinephrine, the participants' correct response was quite poor (43.8%, 6.7%, and 8.6%, respectively). More than 65% of participants could name a single intravenous corticosteroid and antihistamine. Conclusion: Radiology personnel's knowledge regarding contrast material and management of severe contrast material-induced allergic reactions is unsatisfactory.
RESUMO
BACKGROUND: Conventional magnetic resonance imaging (cMRI) is sensitive to motion and ferromagnetic material, leading to suboptimal images and image artifacts. In many patients with neurological injuries, an intracranial bolt (ICB) is placed for monitoring intracranial pressure (ICP). Repeated imaging (computed tomography [CT] or cMRI) is frequently required to guide management. A low-field (0.064-T) portable magnetic resonance imaging (pMRI) machine may provide images in situations that were previously considered contraindications for cMRI. OBSERVATIONS: A 10-year-old boy with severe traumatic brain injury was admitted to the pediatric intensive care unit, and an ICB was placed. Initial head CT showed a left-sided intraparenchymal hemorrhage with intraventricular dissection and cerebral edema with mass effect. Repeated imaging was required to assess the brain structure because of continually fluctuating ICP. Transferring the patient to the radiology suite was risky because of his critical condition and the presence of an ICB; hence, pMRI was performed at the bedside. Images obtained were of excellent quality without any ICB artifact, guiding the decision to continue to manage the patient conservatively. The child later improved and was discharged from the hospital. LESSONS: pMRI can be used to obtain excellent images at the bedside in patients with an ICB, providing useful information for better management of patients with neurological injuries.
RESUMO
INTRODUCTION: Environmental and psychosocial adversities negatively impact children's developmental outcomes. When these factors are experienced in early childhood-a sensitive period of development-the developing brain can be altered. While these associations have been drawn in high-income countries, it is necessary to understand child growth, neurodevelopment, and the role of environmental factors in developmental trajectories in low-income settings. The objective of this study is to longitudinally assess how demographic factors, maternal health, maternal development, and child health, are related to child development on a behavioural, cognitive, and neuroimaging level in low-socioeconomic communities. METHODS AND ANALYSIS: Mother-child dyads will be identified in the peri-urban field sites of Rehri Goth and Ibrahim Hyderi, Karachi, Pakistan. Dyads will undergo yearly assessments for 4 years beginning when the child is 1 month, 3 months or 6 months of age (+≤30 days of age) (depending on group assignment). Maternal assessments include anthropometry, behavioural, cognitive, and developmental assessments (Edinburgh Postnatal Depression Scale; Parenting Stress Index; Maternal Autonomy Index; Hurt, Insult, Threaten, Scream Tool; Reynolds Intellectual Assessment Scales (RIAS)), and biological samples collection (breast milk, blood, stool, hair). Children's assessments include anthropometry, developmental assessments (Global Scales for Early Development (GSED); RIAS), MRI brain assessments, and biological sample collection (blood, stool, hair). Using cross-sectional and longitudinal data with statistical analysis tools, associations will be quantified between brain structure (MRI) and connectivity (resting state connectivity and diffusion tensor imaging), general cognitive skills (RIAS, GSED) and environmental influences (nutrition via biological samples, maternal mental health via questionnaires) through repeated measures analysis of variance tests and χ2 tests. Quantile regression and cortical analyses will be conducted to understand how demographic factors are related to the associations found. ETHICS AND DISSEMINATION: The study has received ethical approval from the Aga Khan University Ethics Review Committee. The study's findings will be disseminated through scientific publications and project summaries for the participants.

BACKGROUND: Prominent leptomeningeal contrast enhancement (LMCE) in the brain is observed in some pediatric patients during sedation for imaging. However, based on clinical history and cerebrospinal fluid analysis, the patients are not acutely ill and do not exhibit meningeal signs. Our study determined whether sevoflurane inhalation in pediatric patients led to this pattern of 'pseudo' LMCE (pLMCE) on 3 Tesla magnetic resonance imaging (MRI). AIM: To highlight the significance of pLMCE in pediatric patients undergoing enhanced brain MRI under sedation to avoid misinterpretation in reports. METHODS: A retrospective cross-sectional evaluation of pediatric patients between 0-8 years of age was conducted. The patients underwent enhanced brain MRI under inhaled sevoflurane. The LMCE grade was determined by two radiologists, and interobserver variability of the grade was calculated using Cohen's kappa. The LMCE grade was correlated with duration of sedation, age and weight using the Spearman rho rank correlation. RESULTS: A total of 63 patients were included. Fourteen (22.2%) cases showed mild LMCE, 48 (76.1%) cases showed moderate LMCE, and 1 case (1.6%) showed severe LMCE. We found substantial agreement between the two radiologists in detection of pLMCE on post-contrast T1 imaging (kappa value = 0.61; P < 0.001). Additionally, we found statistically significant inverse and moderate correlations between patient weight and age. There was no correlation between duration of sedation and pLMCE. CONCLUSION: pLMCE is relatively common on post-contrast spin echo T1-weighted MRI of pediatric patients sedated by sevoflurane due to their fragile and immature vasculature. It should not be misinterpreted for meningeal pathology. Knowing pertinent clinical history of the child is an essential prerequisite to avoid radiological overcalling and the subsequent burden of additional investigations.
RESUMO
Background: Magnetic resonance imaging (MRI) is regarded as the modality of choice in diagnosis of pituitary macroadenomas. Since surgery is the first line therapy for all pituitary adenomas, simple and reproducible MRI classification based on major directions of tumour growth is an essential tool. SIPAP MRI classification for pituitary adenoma describes tumor extension in parasellar, suprasellar, infrasellar, anterior and posterior directions. We, therefore, evaluated reproducibility of SIPAP classification in reporting of pituitary adenomas. Methods: Forty-nine patients with biopsy-proven pituitary macroadenoma were graded according to SIPAP classification. Data was analyzed using Stata version 15. Interobserver variability was calculated using Cohen's Kappa. Comparison between grading before and after treatment was performed by Chi-square test. P values < 0.05 were considered statistically significant. Results: Individual tumour extensions according to SIPAP for pre- and post-operative grading showed significant difference (p-value <0.001), except for anterior extension. For suprasellar extension, 67.3 % patients had pre-operative grade-3 and 63.3 % had post-operative grade-0. For infrasellar extension, 51.0 % had pre-operative grade-2 and 71.4 % had post-operative grade-0. Anterior, posterior and parasellar extensions showed increased frequency in grade-0 in post-operative stage compared to pre-operative. Substantial inter-observer agreement was achieved for Superior, Inferior, Anterior and Posterior extent with all Kappa statistics values above 0.7 (p-value <0.001). Conclusion: We propose incorporating simple and objective SIPAP classification in routine MR reporting for ideal pituitary tumour delineation, relationship to juxtasellar structures and tumour size, hence facilitating greater success rate in surgical and subsequent clinical management.
RESUMO
BACKGROUND: Germinal matrix intraventricular hemorrhage (IVH) may contribute to significant morbidity and mortality in premature infants. Timely identification and grading of IVH affect decision-making and clinical outcomes. There is possibility of misinterpretation of the ultrasound appearances, and the interobserver variability has not been investigated between radiology resident and board-certified radiologist. AIM: To assess interobserver reliability between senior radiology residents performing bedside cranial ultrasound during on-call hours and pediatric radiologists. METHODS: From June 2018 to June 2020, neonatal cranial ultrasound examinations were performed in neonatal intensive care unit. Ultrasound findings were recorded by the residents performing the ultrasound and the pediatric attending radiologists. RESULTS: In total, 200 neonates were included in the study, with a mean gestational age of 30.9 wk. Interobserver agreement for higher grade (Grade III & IV) IVH was excellent. There was substantial agreement for lower grade (Grade I & II) IVH. CONCLUSION: There is strong agreement between radiology residents and pediatric radiologists, which is higher for high grade IVHs.
RESUMO
Objective: To investigate chest radiography findings in suspected coronavirus disease-2019 patients in a tertiary care setting. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of coronavirus disease-2019 cases admitted to the tertiary care centre from March 1 to March 30, 2020. A predesigned proforma was used to gather data, including demographics, like age and gender, co-morbidities, presenting symptoms and chest radiography findings during the admission. Length of stay and mortality were the outcome measures. Data was analysed using SPSS 22. RESULTS: Of the 154 suspected cases, 46(29.8%) tested positive for coronavirus disease-2019; 29(63%) males and 17(37%) females with a mean age of 50.7±19.1 years. Abnormal chest radiography was noted in 25(54.3%) cases, with bilateral pulmonary infiltrates being the most common finding 19(41.3%). Mortality was the outcome in 7(28%) of these cases, and the mean length of hospital stay was 9.3±7.3 days. Abnormal chest radiography findings were associated with an increased risk of mortality (p=0.009) and a longer hospital stay (p=0.017). Conclusion: Abnormal chest radiography findings were frequently seen in coronavirus disease-2019 patients and were also associated with increased risk of mortality and prolonged hospital stay.

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is relatively uncommon in paediatric patients; however, its pathophysiology remains obscure. OBJECTIVE: The aims of this study were to find an association or correlation between (1) blood pressures and (2) imaging severity and the presence of atypical imaging features in children with PRES. MATERIALS AND METHODS: We performed a retrospective cross-sectional evaluation in children diagnosed with PRES. We reviewed radiologic findings along with each patient's clinical profile and outcome. We categorised imaging severity into mild, moderate and severe, and assessed the MR imaging pattern, enhancement and diffusion restriction for each child. We assessed both associations and correlations between variables using the chi-square test, Cramer V and Kendall tau b. RESULTS: A total of 63 children met the inclusion criteria (31 boys; mean age 9.7 years). A total of 42 children (67%) had an elevated blood pressure. Imaging showed parieto-occipital lobe involvement pattern in 24 (38%) children, frontal lobe pattern in 25 (40%) and cerebellar involvement in 12 (19%). Three (5%) had haemorrhage, 15 (24%) had contrast enhancement and 19 (30%) had positive diffusion restriction (cytotoxic oedema). We found no statistically significant association between imaging severity and blood pressures (P=0.11), nor any association between blood pressure and atypical imaging findings such as diffusion restriction (P=0.1), enhancement (P=0.11) or haemorrhage (P=0.33). CONCLUSION: According to our results, there is no statistically significant association or correlation between blood pressure and either imaging severity or atypical imaging features in children with PRES. Further prospective studies are warranted.

BACKGROUND: Though various computerized tomography (CT) severity scores have been described for risk prognostication for coronavirus disease 2019 (COVID-19), most are challenging to calculate and have variable inter-observer agreement. The objective of this study was to develop a simple CT severity score (CT-SS) with good inter-observer agreement and assess its correlation with clinical outcome. METHODS: This retrospective study was conducted at the Aga Khan University Hospital (AKUH), from April-August 2020. All patients who were PCR positive for COVID-19 and underwent CT chest examination at AKUH were included. Severity of disease was described on the basis of a 10-point CT severity score (CT-SS) devised at our institution. CT-SS were categorized as Low (0-7) and High (8-10). Inter-observer reliability between radiologist and COVID-19 intensivist was assessed using the Kappa statistic. RESULTS: A total of 73 patients were included, the majority male (58.9%) with mean age 55.8±13.93 years. The CT-SS rated on 0-10 showed substantial inter-observer reliability between radiologist and intensivist with a Kappa statistic of 0.78. Patients with CT-SS 8-10 had a significantly higher ICU admission & intubation rate (53.8% vs. 23.5%) and mortality rate (35.9% vs. 11.8%; p=0.017), as compared to those with CT-SS 0-7. CONCLUSIONS: We conclude that the described CT severity score (CT-SS) is a quick, effective, and easily reproducible tool for prediction of adverse clinical outcome in patients with COVID 19 pneumonia. The tool shows good inter-observer agreement when calculated by radiologist and physician independently.

OBJECTIVE: To analyse the size and morphology of the normal pineal gland in the paediatric age group using magnetic resonance imaging. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of patients aged <18 years who had magnetic resonance imaging done between 2007 and 2017. Pineal size was estimated measuring its largest anteroposterior and supero-inferior diameters on sagittal T2-weighted sequences on any slice with maximal diameter. The width of pineal gland was measured on axial or coronal T2 sequences. The volume, morphology and enhancement patterns of the gland were also assessed. Data was analysed using SPSS 21. RESULTS: Of the 200 patients, 116(58%) were males and 84(42%) were females. The overall mean age was 7.8±5.5 years. The mean anteroposterior dimension was 4.85±1.46mm, height 3.31±0.95mm, width 4.16±1.19, and volume 39.54±38.12 mm3. Mean size of cyst was 2.77±1.4mm (range: 1.2-7.5mm). No significant differences in the pattern of enhancement were found in different age groups (p>0.05). CONCLUSIONS: Comprehensive knowledge of the size of the typical pineal organ is useful for radiologists in the identification of pineal gland anomalies and the exclusion of neoplastic lesions.

OBJECTIVE: To assess epidemiological, clinical, and radiological characteristics of the coronavirus disease in children and adults. METHODS: The scoping review comprised search on PubMed and Scopus Cochrane databases from January 2020 to April 2021 for English-language articles dealing with clinical and radiological manifestations amongst children and adults affected by coronavirus disease. Two reviewers independently screened the titles and abstracts. RESULTS: Of the 389 studies initially identified, 39(10%) were reviewed in detail. Data suggested that children were less frequently affected by the coronavirus disease. The affected children showed milder disease with low case fatalities compared to the adults. CONCLUSIONS: There exists significant gaps in knowledge of clinical and radiological aspects of coronavirus disease, but the available scientific data showed that the disease seems to be unusual in children.

BACKGROUND: Hydatid disease caused by Echinococcus granulosus commonly involves the liver followed by lungs. Cardiac involvement is a rare occurrence and presents a challenging scenario. CASE PRESENTATION: Our case describes a middle-aged gentleman who presented to the emergency room with an episode of sudden loss of consciousness resulting from ventricular tachycardia. After successful cardiac resuscitation, the patient underwent imaging that showed a lesion compatible with hydatid cyst. Surgical treatment with pharmacologic coverage was provided which resulted in good clinical outcome. CONCLUSIONS: The case highlights rare occurrence of isolated cardiac hydatid disease presenting as cardiac arrhythmia in contrast to its common routine outpatient presentation involving the liver and lungs. Good knowledge of the unusual presentations and its epidemiology is essential to the proper management of such patients.
RESUMO
INTRODUCTION: Thyroid incidentalomas (TIs) are clinically asymptomatic nodules found accidentally during imaging studies ordered for some other reasons. Being easily accessible, non-invasive, and inexpensive, thyroid ultrasound (US) is a key investigation in the management of thyroid nodules. METHODS: This ultrasound-based cross-sectional study was performed in the radiology department of a major tertiary care hospital. Every second patient visiting the emergency department was a potential candidate for a thyroid ultrasound. Patients having ages greater than 20 years were included in the study. RESULTS: A total of 250 patients were included in the study. Out of these, 175 were female and 75 were male. The majority (54.80%) were in the age group 21-30 years. Nodules were found in 65 (26%) patients and in the majority of cases (67.7%) they were multiple in number. Associated lymphadenopathy was seen in only one patient. Thyroid nodules were more common in females as compared to males (75.38% versus 24.62%). According to Thyroid Imaging and Reporting Data System (TI-RADS) classification, the majority of the nodules were falling in TI-RADS 1 (74%) followed by TI-RADS 3 (9.60%) and 4A (8.80%). CONCLUSION: The thyroid nodules are more commonly seen in females as compared to males. A significant association is seen between the frequency of thyroid nodules and increasing age. The majority of thyroid nodules fall in TI-RADS 1 category followed by TI-RADS 3 and 4A.
RESUMO
INTRODUCTION: While chest x-rays (CXRs) represent a cost-effective imaging modality for developing countries like Pakistan, their utility for the prognostication of COVID-19 has been minimally explored. Thus, we describe the frequency and distribution of CXR findings, and their association with clinical outcomes of patients with COVID-19. METHODS: All adult (≥ 18 years) patients presenting between 28th February-31st May to the emergency department of a tertiary care hospital in Pakistan, who were COVID-19 positive on RT-PCR with CXR done on presentation, were included. A CXR Severity Score (CXR-SS) of 0-8 was used to quantify the extent of pulmonary infection on CXR, with a score of 0 being negative and 1-8 being positive. The patients' initial CXR-SS and their highest CXR-SS over the hospital course were used for analysis, with cut-offs of 0-4 and 5-8 being used to assess association with clinical outcomes. RESULTS: A total of 150 patients, with 76.7% males and mean age 56.1 years, were included in this study. Initial CXR was positive in 80% of patients, and 30.7% of patients had an initial CXR-SS between 5-8. The mortality rate was 16.7% and 30.6% patients underwent ICU admission with intubation (ICU-Int). On multivariable analysis, initial CXR-SS (1.355 [1.136-1.616]) and highest CXR-SS (1.390 [1.143-1.690]) were predictors of ICU-Int, and ICU-Int was independently associated with both initial CXR-SS 5-8 (2.532 [1.109-5.782]) and highest CXR-SS 5-8 (3.386 [1.405-8.159]). Lastly, age (1.060 [1.009-1.113]), initial CXR-SS (1.278 [1.010-1.617]) and ICU-Int (5.047 [1.731-14.710]), were found to be independent predictors of mortality in our patients. CONCLUSION: In a resource-constrained country like Pakistan, CXRs may have valuable prognostic utility in predicting ICU admission and mortality. Additional research with larger patient samples is needed to further explore the association of CXR findings with clinical outcomes.

The cells in glomus body regulate blood flow to the skin and play a role in temperature regulation. Glomuvenous malformations (GVMs), previously reported in literature as glomus tumors or glomangiomas, are usually present in the nail bed. In 1972, Carroll and Berman described the triad of paroxysmal stabbing pain, point tenderness, and cold hypersensitivity associated with these malformations. We present an unusual case of GVM in the neck of a 17-year-old female presenting with a painful right-sided neck mass. Physical examination revealed an approximately 2.5 × 2 cm right-sided tender neck mass; pain was exacerbated by probing with a pinhead. Computed tomography identified multiple rounded masses in the neck, with the delayed contrast filling. The patient underwent excisional biopsy of the lesion and samples were sent for histopathological examination. The histopathology report, along with the radiological findings and the clinical presentation, confirmed the diagnosis of GVM. The patient remained symptom-free on long-term follow-up. Despite absence of previous reports, GVM can occur in neck. Surgical excision can lead to complete resolution of symptoms.
