ABSTRACT
In Jeju Island, South Korea, a patient who consumed raw pig products had subdural empyema, which led to meningitis, sepsis, and status epilepticus. We identified Streptococcus suis from blood and the subdural empyema. This case illustrates the importance of considering dietary habits in similar clinical assessments to prevent misdiagnosis.

INTRODUCTION: Intracranial infection is often associated with contiguous sinus infection, with Streptococcus intermedius being the most common pathogen. Microbiological assessment is possible via sinus or intracranial sampling. While a sinus approach is minimally invasive, it is not clear whether this yields definitive microbiological diagnosis leading to optimized antimicrobial therapy and avoidance of intracranial surgery. METHODS: A retrospective review of a prospectively collected electronic departmental database identified patients between 2019 and 2022. Further demographic and microbiological information was obtained from electronic patient records and laboratory management systems. RESULTS: Thirty-one patients were identified with intracranial subdural and/or epidural empyema and concurrent sinus involvement during the 3-year study period. The median age of onset was 10 years with a slight male predominance (55%). All patients had intracranial sampling with 15 patients undergoing sinus sampling in addition. Only 1 patient (7%) demonstrated identical organism(s) grown from both samples. Streptococcus intermedius was the most common pathogen in intracranial samples. Thirteen patients (42%) had mixed organisms from their intracranial cultures and 57% of samples undergoing bacterial PCR identified additional organisms, predominantly anaerobes. Sinus samples had a significant addition of nasal flora and Staphylococcus aureus which was rarely grown from intracranial samples. Of concern, 7/14 (50%) of sinus samples did not identify the main intracranial pathogen diagnosed on intracranial culture and additional PCR. Literature review identified 21 studies where sinus drainage was used to treat intracranial empyemas, with only 6 authors reporting concurrent microbiology results. This confirmed our cohort to be the largest comparative study in the current literature. No center has observed a greater than 50% concordance in microbiological diagnoses. CONCLUSION: Endoscopic sinus surgery may have therapeutic benefit, but it is not an appropriate approach for microbiological diagnosis in pediatric subdural empyemas. High rates of contaminating nasal flora can lead to misdiagnosis and inappropriate treatment. Routine addition of 16S rRNA PCR to intracranial samples is recommended.

BACKGROUND: Data on critically ill patients with spontaneous empyema or brain abscess are limited. The aim was to evaluate clinical presentations, factors, and microbiological findings associated with the outcome in patients treated in a Neurocritical Care Unit. METHODS: In this retrospective study, we analyzed 45 out of 101 screened patients with spontaneous epidural or subdural empyema and/or brain abscess treated at a tertiary care center between January 2012 and December 2019. Patients with postoperative infections or spinal abscess were excluded. Medical records were reviewed for baseline characteristics, origin of infection, laboratory and microbiology findings, and treatment characteristics. The outcome was determined using the Glasgow outcome scale extended (GOSE). RESULTS: Favorable outcome (GOSE 5-8) was achieved in 38 of 45 patients (84%). Four patients died (9%), three remained severely disabled (7%). Unfavorable outcome was associated with a decreased level of consciousness at admission (Glasgow coma scale < 9) (43% versus 3%; p = 0.009), need of vasopressors (71% versus 11%; p = 0.002), sepsis (43% versus 8%; p = 0.013), higher age (65.1 ± 15.7 versus 46.9 ± 17.5 years; p = 0.014), shorter time between symptoms onset and ICU admission (5 ± 2.4 days versus 11.6 ± 16.8 days; p = 0.013), and higher median C-reactive protein (CRP) serum levels (206 mg/l, range 15-259 mg/l versus 17.5 mg/l, range 3.3-72.7 mg/l; p = 0.036). With antibiotics adapted according to culture sensitivities in the first 2 weeks, neuroimaging revealed a progression of empyema or abscess in 45% of the cases. CONCLUSION: Favorable outcome can be achieved in a considerable proportion of an intensive care population with spontaneous empyema or brain abscess. Sepsis and more frequent need for vasopressors, associated with unfavorable outcome, indicate a fulminant course of a not only cerebral but systemic infection. Change of antibiotic therapy according to microbiological findings in the first 2 weeks should be exercised with great caution.

Subdural empyema (SDE) is a rare condition which can appear secondary to meningitis in childhood, especially in infants. This study was planned to evaluate and compare clinical and laboratory features, treatment, and outcome of children with SDE to those with acute bacterial meningitis (ABM) without SDE. The electronic medical files of 266 patients diagnosed with ABM between January 2009 and December 2019 were evaluated. Patients' demographic and clinical features, laboratory results, cranial imaging findings, treatment, and outcomes were recorded. SDE was identified in 10 patients, 3.7% of all diagnosed with meningitis. The etiology of SDE was identified in eight (80%). The most common responsible pathogen was Streptococcus pneumoniae. Cranial imaging was performed between the 2nd and 13th days of admission, and the most common reason of performing cranial imaging was persistence of fever. Two patients were healed with 4-6 weeks of antibiotic treatment without surgery, eight (80%) needed surgical intervention.Conclusion: The clinical signs and symptoms of SDE may be subtle. If the fever persists or focal neurological findings are seen during the treatment of bacterial meningitis, SDE should be suspected. Furthermore, patients with ABM who are determined to have a protein-to-glucose ratio in the cerebrospinal fluid above 4.65 should be carefully monitored for SDE development. What is known: ⢠Subdural empyema may develop subsequently to meningitis, especially in the infant age group in whom very little is known in terms of disease characteristics. ⢠Delay in diagnosis and treatment can cause long-term neurologic sequelae and mortality. What is new: ⢠Persistence or relapse of fever during the treatment of acute meningitis is an important warning sign for SDE even if there are no other symptoms. ⢠Children with subdural empyema secondary to bacterial meningitis have higher protein-to-glucose ratio in the CSF, and a threshold of Ë 4.65 was determined to demonstrate 100% sensitivity and 50.7% specificity.

BACKGROUND: Despite technological advances in medical treatment, the prognosis of the rarely reported spinal subdural abscesses (SSAs) has remained a serious entity largely unaffected, especially when they are diagnosed late. In this study, the authors aimed to present the surgical outcomes of 3 consecutive pediatric patients with SSA. MATERIALS AND METHODS: We retrospectively reviewed the medical records of pediatric patients with spinal lesions who underwent surgery at 2 neurosurgical centers spanning 7 years, from 2012 to 2019. All pediatric patients who were diagnosed with SSA (n = 3) were selected as the core sample for this study. RESULTS: Three pediatric patients (2 females and 1 male) with SSA were surgically treated. Holocord SSA was observed in 1 patient. The mean age was 7.1 ± 7.7 years. The most common presenting symptoms were gait disturbance and weakness of lower extremities (100%). The mean preoperative course was 5.7 ± 4.0 weeks. The causative pathogens were Escherichia coli (E. coli) and M. tuberculosis. In the 2nd case, the pathogen was non-tuberculosis mycobacterium in the extramedullary abscess. In the 44th postoperative month, she underwent surgery for intramedullary abscess. The causative pathogen was E. coli. Except for 1 male adolescent who presented with severe clinical status (paraplegic), the improvement was observed in all patients at their last follow-up after 50.3 ± 43.5 months of average. CONCLUSIONS: Drainage followed by appropriate antibiotics is the optimal treatment for SSAs. Early diagnosis and urgent surgical treatment are essential for a good prognosis. All surgically treated SSA patients with neurological deficits were rehabilitated with physical therapy postoperatively.

BACKGROUND: We report a case of subdural empyema in a homeless patient caused by Bartonella quintana. B. quintana is a facultative intracellular bacteria for which bacterial growth is fastidious. The molecular biology approach has been a real help in establishing the diagnosis. CASE REPORT: A 59-years old homeless patient, with a history of chronic alcohol abuse, was brought to the emergency department with a massive subdural empyema. Extensive microbiological evaluation didn't reveal any pathogen in the pus collected before antibiotic treatment. B. quintana was detected in the pus from the empyema using a 16S rRNA-based PCR. Histology of intraoperative samples was consistent with the diagnosis and a serological assay was positive. The patient responded well to a treatment that included craniectomy with drainage of the loculated pus, total removal of the infected capsule and a combination of antibiotics. CONCLUSION: This unique case of B. quintana-related empyema illustrates the risk of secondary infection of subdural hematoma with B. quintana since such infections have recently reemerged, predominantly among the homeless populations. Patients with subdural empyema in at-risk populations should be systematically evaluated for B. quintana with an appropriate diagnostic approach involving molecular biology.

A case report of a 94-year-old, previously well male patient who presented with fever thought to be caused by community acquired pneumonia, new unilateral hearing loss and reduced consciousness. Despite antibiotic treatment he continued to deteriorate. Brain imaging with computer tomography and magnetic resonance imaging revealed a left otomastoiditis with osteomyelitis of the skull base, associated with an adjacent subdural empyema. He was also found to have a venous sinus thrombosis, most likely secondary to otitis media. He was managed with intravenous antibiotics, anticoagulation, grommet insertion and a hearing aid and he made a good recovery. This case reminds us to consider otitis media in older patients who present with hearing loss and fever. Otitis media can lead to serious complications including subdural empyema and osteomyelitis of the skull base.

OBJECTIVE: The aim of this study was to report the etiology, clinical features, microbiology, surgical outcome, and predictors of outcome of spontaneous subdural empyema (SDE). METHODS: The authors conducted a retrospective study in a tertiary hospital. Children up to 18 years of age, with a diagnosis of SDE with infective etiology, were included in the present cohort. Patients with posttraumatic, postsurgery, and tubercular origin of SDE were excluded from the study. The Glasgow Outcome Scale was used for outcome assessment at the end of 3 months. For analysis purposes, the demographic data, clinical features, radiological data, microbiology, type of surgery, and complication data were categorized, and univariate and multivariable logistic regression analyses were performed to identify the factors associated with outcome. RESULTS: Ninety-eight children were included in the study and the mean age was 10.9 years. Otogenic origin (34.7%) was the most common source of infection, followed by meningitis (14.3%). The mean duration of symptoms was 12 days. Seventy-six children presented with Glasgow Coma Scale (GCS) score > 8 and the supratentorial location was the most common location. Almost 75% of the children underwent craniotomy or craniectomy and the rest had burr-hole evacuation. Beta-hemolytic Streptococcus (10%) was the most common organism isolated. Cerebral venous thrombosis (CVT; 10.2%) was the most frequent complication in this cohort. The other complications were infarction (6.1%), new-onset seizure (4.1%), and bone flap osteomyelitis (4.1%). Thirteen cases had a recurrence of pus collection, which was more common in the craniotomy group than in the burr-hole group. Age (p = 0.02), GCS score ≤ 8 (OR 8.15, p = 0.001), CVT (OR 15.17, p = 0.001), and presence of infarction (OR 7, p = 0.05) were strongly associated with unfavorable outcome. In multivariable logistic regression analysis, only GCS score ≤ 8 (p = 0.01), CVT (p = 0.02), and presence of infarction (p = 0.04) had a significant impact on unfavorable outcome. CONCLUSIONS: Prompt diagnosis and immediate intervention is the goal of management of SDE, especially in children as a delay in diagnosis can result in unconsciousness and secondary complications such as CVT and infarction, which adversely affect outcome.

We present a rare case of subdural empyema with cerebral arteritis and brain ischemia in the middle cerebral artery distribution secondary to odontogenic maxillary sinusitis. A 32-year-old man was admitted to our hospital because of high fever and generalized convulsions. Computed tomography(CT)and magnetic resonance imaging(MRI)showed subdural empyema at the left convexity, with a small amount of air. An interruption of the right maxillary sinus floor corresponding to the alveolar process was evident on coronal CT. He was diagnosed as having subdural empyema caused by odontogenic maxillary sinusitis. MR angiography showed stenosis of the left middle cerebral artery(MCA). Despite antibiotic administration, he became drowsy and developed aphasia with right hemiparesis. Repeat MRI showed enlargement of the encapsulated subdural empyema with increased midline shift to the right. We performed prompt surgical evacuation with craniotomy, endoscopic drainage of the sinusitis, and tooth extraction. A hyperintense lesion was observed on subsequent diffusion-weighted imaging in the left MCA distribution. After repeat drainage of the re-enlarged subdural empyema, he was discharged without apparent neurological deficits. This case indicates that subdural empyema from odontogenic sinusitis requires a suitable imaging study of the brain, head, and neck region, and a multidisciplinary approach involving a neurosurgeon, otolaryngologist, and oral surgeon. Prompt initiation of appropriate antibiotic therapy with surgical intervention is recommended for treatment of subdural empyema from odontogenic sinusitis.

PURPOSE: To describe the presentation and management of bacterial brain abscess and subdural empyema in adults treated at two tertiary centers. In addition, to identify factors that may predict a poor clinical outcome. METHODS: A retrospective analysis of data obtained from clinical records was performed, followed by multivariate regression analysis of patient and treatment-related factors. RESULTS: 113 patients were included with a median age of 53 years and a male preponderance. At presentation symptoms were variable, 28% had a focal neurological deficit, and 39% had a reduced Glasgow coma scale (GCS). Brain abscesses most frequently affected the frontal, temporal, and parietal lobes while 36% had a subdural empyema. An underlying cause was identified in 76%; a contiguous ear or sinus infection (43%), recent surgery or trauma (18%) and haematogenous spread (15%). A microbiological diagnosis was confirmed in 86%, with streptococci, staphylococci, and anaerobes most frequently isolated. Treatment involved complex, prolonged antibiotic therapy (> 6 weeks in 84%) combined with neurosurgical drainage (91%) and source control surgery (34%). Mortality was 5% with 31% suffering long-term disability and 64% achieving a good clinical outcome. A reduced GCS, focal neurological deficit, and seizures at presentation were independently associated with an unfavorable clinical outcome (death or disability). CONCLUSIONS: Complex surgical and antimicrobial treatment achieves a good outcome in the majority of patients with bacterial brain abscess and subdural empyema. Factors present at diagnosis can help to predict those likely to suffer adverse outcomes. Research to determine optimal surgical and antibiotic management would be valuable.

Intracranial complications of paranasal sinusitis have become rare due to the use of antibiotics nowadays. However, several cases have been reported due the ability of paranasal sinusitis to cause serious complications. Once the infection spreads over the cranial structure, it could infect the orbits, underlying bones, meninges, adjacent veins, and brain. Subdural empyema is a rare but potentially life-threatening complication following paranasal sinusitis and should be considered as a neurological emergency. The location where subdural empyema may appear is a challenge in diagnosis and treatment. We report the case of a 17-year-old boy who presented in a state of somnolence due to interhemispheric and infratentorial subdural empyema with preseptal cellulitis secondary to pansinusitis. Early diagnosis and aggressive antibiotic treatment combined with neurosurgical operation were mandatorily implemented. The case was managed using a multidisciplinary approach including the ENT, eye, and nutrition departments. The boy achieved clinical improvement, with impairment of eye movement as the only persistent symptom before discharge. Daily supervision at the primary health care center with continuous antibiotic treatment was recommended to the patient. Pertinent literature with controversies in the management of subdural empyema will be briefly discussed in this case report.

BACKGROUND: Controversy regarding the best management strategy for subdural empyema (SDE) attests to the persisting poor outcomes for this uncommon life threatening intracranial suppurative process. Late presentation confounds the problem in developed countries. While craniotomy is commonly recommended, it is not always possible in late presentation with advanced morbidity. The aim of this study was to identify the pattern of clinical presentation and explore the outcomes following management of SDE using burr hole, aspiration, and drainage (BAAD) in resource poor settings. MATERIALS AND METHODS: This is a retrospective review of prospectively collected data of 18 patients presenting with SDE over a period of 10 years from two neurosurgical centers. Data was abstracted on patients' demographic characteristics, sources of SDE, clinical presentation and site of infection, methods of diagnosis, organisms isolated, treatments received, and outcome. Collected data was entered into the Statistical Package for the Social Sciences version 17 software and subjected to descriptive analysis for all variables. RESULTS: Majority of the patients presented late with Glasgow Coma Scale score GCS of 9/15. Altered sensorium was noted in 14 (77.8%) of the patients, 11 (61.1%) out of the 14 patients had ≤ grade 3 of Bannister and Williams level of consciousness. The mainstay of treatment for all patients was BAAD of abscess and administration of appropriate antibiotics. Fourteen patients (77.8%) were discharged on grade A of H.W. Mauser's grading system. Three mortalities were recorded only in patients who had grade 4 Bannister and Williams grading. CONCLUSION: BAAD is the near approximated option to standard craniotomy management in a limited resource facility and it has a very good clinical outcome. However, more studies are required to draw the final conclusion.

Hereditary haemorrhagic telangiectasia (HHT) also known as Osler-Weber-Rendu disease is a rare autosomal dominant condition causing vascular dysplasia. Cerebral abscess formation, secondary to paradoxical septic emboli via HHT-derived pulmonary arteriovenous malformations (pAVMs) in this context is well documented. Herein, we present the first case of subdural empyema with this aetiology.

This work analyzed 47 cases of oto- and rhinosinusogenic suppurative meningoencephalitis, abscesses and empyemas of the brain in children at the age from 3 months to 17 years old. The article presents the treatment strategy, results and the volume of diagnostic measures. On the basis of this research, the authors came to conclusion, that care of the children with otogenic and rhinosinusogenic suppurative diseases of the brain required an interdisciplinary approach and effective cooperation of a neurosurgeon, otolaryngologist, pediatrician, resuscitation specialist, infectionist and a clinical pharmacologist.

Mycoplasma hominis is a commensal of the genitourinary tract, which is infrequently associated with urogenital infections. Extra-urogenital infections due to M. hominis are rare. Here, we report an unusual case of M. hominis subdural empyema in a woman occurring shortly after delivery. The patient presented with symptoms suggestive of bacterial meningitis. Spinal imaging revealed a subdural empyema that required neurosurgical intervention. Cultures from intraoperatively obtained biopsies identified M. hominis as the causative pathogen. The patient was treated with oral moxifloxacin for 4 weeks resulting in the resolution of the spinal lesion. The subdural empyema was presumably caused by a contaminated epidural blood patch performed with the patient's own blood during an episode of transient M. hominis bacteremia after delivery. The blood patch was indicated for the treatment of cerebrospinal fluid leakage, which had occurred after epidural anesthesia. Our findings highlight the significance of transient M. hominis bacteremia after delivery and implicate that M. hominis should be considered as a causative agent of extra-genitourinary tract infections particularly during the postpartum period or after genitourinary manipulation.

We investigated the utility of procalcitonin in early diagnosis of bacterial central nervous system (CNS) infection. Serum procalcitonin level was markedly elevated in the patients with systemic meningitis but not in the patients with brain abscess and subdural empyema. Procalcitonin may be useless to diagnose focal bacterial CNS infection.

Headache caused by subdural empyema is usually associated with fever and symptoms and/or clinical signs of meningeal irritation and increased intracranial pressure. We describe a patient with headache with absence of these signs or symptoms of meningeal irritation or intracranial pressure, who turned out to have a parafalcine subduralempyema. A 28-year-old man had headache for 2 weeks, which had started with visual symptoms with duration of 5 minutes. Two days later, he developed fever. During these 2 weeks, he had recurrence of visual symptoms for 4 times, with duration of several minutes.Neurologic examination at presentation on the emergency department showed no meningeal irritation or papilledema. However, on closer examination, a limited homonymous hemianopsia on the left side and a drift of the left leg were found. Magnetic resonance imaging showed parafalcine subdural empyema on the right side of the falx and a small brain abscess right occipitally. Neuronavigated craniotomy was performed, which confirmed the presence of empyema and allowed culture of the specimens. Streptococcus milleri group was cultured,which allowed narrowing of the antibiotic therapy to Benzylpenicillin12 million entities per 24 hours. Headache and subdural empyema diminished during treatment, and at follow-up 12 weeks after start of treatment, patient had no remaining complaints. Parafalcine-located subdural empyema can present without presence of clear localizing symptoms or signs like meningeal irritation and increased intracranial pressure. When headache is accompanied with fever, one should extensively question neurologic symptoms, and a thorough neurologic examination should be done.

BACKGROUND AND OBJECTIVES: Pediatric subdural empyemas (SDE) carry significant morbidity and mortality, and prompt diagnosis and treatment are essential to ensure optimal outcomes. Nonclinical factors affect presentation, time to diagnosis, and outcomes in several neurosurgical conditions and are potential causes of delay in presentation and treatment for patients with SDE. To evaluate whether socioeconomic status, race, and insurance status affect presentation, time to diagnosis, and outcomes for children with subdural empyema. METHODS: We conducted a retrospective cohort study with patients diagnosed with SDE between 2005 and 2020 at our institution. Information regarding demographics (age, sex, zip code, insurance status, race/ethnicity) and presentation (symptoms, number of prior visits, duration of symptoms) was collected. Outcome measures included mortality, postoperative complications, length of stay, and discharge disposition. RESULTS: 42 patients were diagnosed with SDE with a mean age of 9.5 years. Most (85.7%) (n = 36) were male ( P = .0004), and a majority, 28/42 (66.7%), were African American ( P < .0001). There was no significant difference in socioeconomic status based on zip codes, although a significantly higher number of patients were on public insurance ( P = .015). African American patients had a significantly longer duration of symptoms than their Caucasian counterparts (8.4 days vs 1.8 days P = .0316). In total, 41/42 underwent surgery for the SDE, most within 24 hours of initial neurosurgical evaluation. There were no significant differences in the average length of stay. The average length of antibiotic duration was 57.2 days and was similar for all patients. There were no significant differences in discharge disposition based on any of the factors identified with most of the patients (52.4%) being discharged to home. There was 1 mortality (2.4%). CONCLUSION: Although there were no differences in outcomes based on nonclinical factors, African American men on public insurance bear a disproportionately high burden of SDE. Further investigation into the causes of this is warranted.

OBJECTIVE: To describe and compare clinical and microbiological features, surgical and medical management, and outcomes of children with otogenic and sinogenic intracranial empyema (IE) in an institution with an established multidisciplinary protocol. To use the study findings to inform and update the institutional algorithm. METHODS: Retrospective analysis was carried out on the electronic healthcare records of all children with oto-sinogenic IE admitted in a 5-year period. RESULTS: A total of 76 patients were identified and treated according to an institutional protocol. Two distinct groups were identified: intracranial empyema related to otogenic infection (OI-IE, n = 36) or sinogenic infection (SI-IE, n = 40). SI-IE was seen in older children and had a significantly higher morbidity. Sub-dural IE was seen in a minority (n = 16) and only in SI-IE and required urgent collaborative ENT-neurosurgery. Extra-dural IE occurred more frequently and was seen in both SI-IE and OI-IE. No death and overall low morbidity were observed. Particularities found in SI-IE and OI-IE groups (as thrombosis, microbiology, antibiotic treatment, duration and outcome) permitted the delineation of these groups in our updated algorithm. CONCLUSION: The presence of a collaborative multidisciplinary protocol permits the step-wise co-ordination of care for these complex patients in our institution. All patients received prompt imaging, urgent surgical intervention, and antibiotic treatment. Microbiological identification was possible for each patient and antibiotic rationalization was permitted through use of Polymerase chain reaction (PCR) testing in cases of sterile cultures. Of note, intracranial empyema related to sinogenic infection is shown to have significantly more severe clinical presentation, a higher morbidity, and a longer duration of antibiotic therapy than that related to otogenic infection. Study findings allowed for the update and clarification of the institutional protocol, which now clearly demarcates the clinical presentation, biological evidence, radiology, surgical and medical treatments in children with oto-sinogenic IE.

BACKGROUND/AIM: Although chemotherapy for colorectal cancer has advanced remarkably, long-term chemotherapy can lead to a variety of infections. However, if chemotherapy must be discontinued to control infection, there is a risk of progression of colorectal cancer. Intracranial subdural empyema is a life-threatening intracranial infection. The condition requires 6-8 weeks of antibiotic therapy, and the patient must discontinue chemotherapy during treatment. We herein present a case of intracranial subdural empyema during long-term chemotherapy for metastatic rectal cancer. CASE REPORT: A 69-year-old woman with unresectable metastatic rectal cancer had a convulsive seizure and was admitted to our hospital. The cause of the convulsive seizure was considered a metastatic brain tumor from rectal cancer. However, on the basis of contrast-enhanced computed tomography and contrast-enhanced magnetic resonance imaging, we diagnosed intracranial subdural empyema. The infection was controlled by antibiotics, but chemotherapy for rectal cancer was discontinued during antibiotic treatment. As a result, the rectal cancer progressed, and the patient died 65 days after admission to our hospital. CONCLUSION: Intracranial subdural empyema may develop rarely during chemotherapy. This condition requires long-term treatment with antibiotics; therefore, early detailed imaging and diagnosis may improve the prognosis.
