ABSTRACT
Background: Intracranial lipomas are a rare clinical entity. These lesions are frequently asymptomatic and originate in the pericallosal area. As they are fat-containing lesions which are intimately attached to the surrounding structures, surgery is not recommended. In some individual reports, subtotal resection is recommended to lessen complications. There have been no previous reports of corpus callosum lipoma (CCL) associated with limited dorsal myeloschizis (LDM). Case Description: We describe the case of a combination of CCL and bilateral choroid plexus lipoma discovered incidentally during the investigation of LDM in a 3-month-old male child. Given the asymptomatic behavior of the lipoma and the vascular elements of the pericallosal area, it was decided to monitor it regularly. Thus, the patient underwent surgery only for LDM. Histological examination confirmed the diagnosis, and postoperative follow-up 1 year after showed good evolution. To the best of our knowledge, this association has never been described in the literature. Conclusion: This case suggests a possible developmental relationship between CCL and spinal dysraphism.
ABSTRACT
INTRODUCTION: Spontaneous spinal epidural hematoma (SSEH) is a rare entity, especially in toddlers and infants. The nonspecificity of its presenting symptoms in children may be a source of delayed diagnosis. CASE DESCRIPTION: We report the case of a 20-month-old young boy without medical history who presented with irreducible torticollis, worsened a few days later by severe tetraplegia and respiratory distress. Spinal magnetic resonance imaging (MRI) showed a posterior epidural hematoma, extending from C3 to T1 and compressing the spinal cord. An urgent decompressive surgery via an extensive laminectomy and evacuation of the clot was performed. The patient demonstrated a partial neurological recovery on follow-up. CONCLUSION: SSEH is a rare and serious condition that may compromise the functional and vital prognosis of the patient, hence the importance of prompt diagnosis and urgent treatment.

Central nervous system (CNS) tuberculosis is a potentially life-threatening condition that may manifest in different forms and simulate other pathologies. It rarely involves the ventricles and the occurrence of primary intraventricular tuberculous brain abscess (TBA) has exceptionally been reported. As far as we know, ruptured intraventricular TBA has not been described before. An immunocompetent 56-years-old man was admitted for sub-acute intracranial hypertension with behaviour disorders. Cranial magnetic resonance imaging (MRI) showed a cystic lesion of the third ventricle containing fluid-fluid level with biventricular hydrocephalus and debris in the occipital horns. A ruptured cystic neoplasm was first considered. The patient underwent surgery via a right transcortical transventricular approach, combining both microscope and endoscope. The puncture of the lesion brought pus and the Ziehl-Neelson (ZN) staining demonstrated acid-fast bacilli. Intraventricular tuberculous abscess is an extremely rare condition that can take an unusual radiological appearance. This observation highlights the consideration of tuberculosis within the list of differential diagnosis of intraventricular cystic lesions in immunocompetent hosts.

Arachnoiditis ossificans of the spine is a rare entity defined as an ossification of the leptomeninges resulting in neurologic decline. We describe the case of a 42-year-old woman, without any obvious predisposing factor, who presented with a progressive cauda equina syndrome. The imaging findings on magnetic resonance imaging were confusing by showing an atypical intraspinal lesion extending from L1 to S1. The computed tomography scan was more specific by showing suggestive images of a huge arachnoiditis ossificans of the lumbar spine. The patient underwent a large lumbar laminectomy with an incomplete resection of the ossified arachnoid. The histologic study confirmed the bony nature of the lesion. This illustrative case highlights the importance of helical computed tomography scan with multiplanar reconstruction for the diagnosis of arachnoiditis ossificans.

Infection with the new coronavirus has been declared an international health emergency. Its curative treatment is unknown and is the subject of several clinical trials. In addition, the concomitant association of COVID-19 with tuberculosis and the human immunodeficiency virus, hitherto never described, is potentially fatal. We report the illustrative case of a 32-year-old patient who presented this trifecta of infections and who did well under treatment with chloroquine and anti-mycobacterial drugs. This patient arrived at the ER with respiratory discomfort that had been evolving over a month with symptoms of flu and deterioration of her general condition. A chest CT scan revealed an aspect of lung miliary tuberculosis with isolation of Koch's bacilli in the sputum. A polymerization chain reaction (PCR) was positive for COVID-19 on a nasopharyngeal swab. HIV serology was positive. The course was marked by a spectacular clinical improvement and two negative COVID-19 PCR controls at the end of treatment (at days 9 and 10). Anti-tubercular drugs (especially, rifampin) are powerful enzyme inducers that can reduce the effectiveness of chloroquine in our patient. This therapeutic success may be linked to the effect of anti-tubercular drugs against SARS ncov-2, especially rifampin, inhibiting the formation of messenger RNAs of SARS ncov-2 or to the synergistic effect of chloroquine and rifampin. Researchers should explore the effect of these drugs on SARS ncov-2.

BACKGROUND: Awake craniotomy with brain mapping aims to maximize resection of gliomas located within eloquent regions while minimizing the risk of postoperative deficits. This technique is common practice in the developed world but has yet to be implemented in most low- and middle-income countries (LMICs). We assessed the feasibility, safety, and efficiency of functional-based glioma resection using minimal facilities in a limited-resource institution. METHODS: This is a retrospective review of patients harboring gliomas within eloquent regions who underwent awake craniotomy and tumor resection guided by cortico-subcortical mapping at a tertiary hospital of an LMIC. Patient characteristics, surgical results, and functional outcomes were studied. RESULTS: Twenty consecutive patients with a mean age of 37 years were enrolled in the study. Seizure, present in 70% of patients, was the major presenting symptom. Eighteen patients had diffuse low-grade gliomas and 2 patients had high-grade gliomas. Intraoperative events were dominated by seizures, occurring in 5 patients (25%). The average extent of tumor removal was 89.5% and the rate of total and subtotal removal was 85%. New postoperative deficits were observed in 5 patients (25%), and permanent deficits were found in 1 patient (5%). The main hurdles encountered were the difficulties in investigating patients and human resource availability. CONCLUSIONS: Awake craniotomy with brain mapping for functional-based resection of gliomas can be safely achieved in a limited-resource institution with good functional and oncologic results.

BACKGROUND: Traumatic spinal subdural hematoma is an extremely rare occurrence that requires urgent investigation and most often prompt intervention. To our knowledge, this is the first reported case related to a spinal manipulative therapy. CASE DESCRIPTION: This report describes a case of traumatic lumbar subdural hematoma after a spinal manipulative therapy without any predisposing factor. A 23-year-old man was admitted to the emergency department for partial cauda equina syndrome after a spinal manipulation performed by a physiotherapist. Magnetic resonance imaging showed an acute spinal subdural hematoma at L2-L3 level with cauda equina compression. The patient underwent an emergency L2 laminectomy with evacuation of the hematoma. He recovered completely his neurologic functions after 1 week. CONCLUSION: Practitioners of spinal manipulations should be aware of spinal subdural hematoma as a possible complication. A rapid diagnosis with magnetic resonance imaging is mandatory, and emergency surgical decompression is usually the optimal treatment for spinal subdural hematomas with severe neurologic deficit.

Nasofrontal fistulas correspond to the persistence of an abnormal communication of embryological origin between the deep layer of the skin and the central nervous system (CNS). They can rarely be associated with a dermoid cyst and be revealed by a locoregional infection, and especially neuromeningeal infections can be serious. The treatment is mainly surgical by performing a total excision of the cyst and the repair of defects. The authors report the case of an 18-month-old infant operated for a dermoid cyst revealed by a nasofrontal fistula. They insist on the characteristics of this pathology in order to establish a diagnosis and an early treatment to avoid the complications that can be heavy in certain cases. They describe the steps of nasofrontal reconstruction by a small flap taken from the outer table of the frontal bone with better esthetic results.
ABSTRACT
Our study is a retrospective analysis of the clinical data, surgical outcomes, histological finding and prognosis of foramen magnum meningiomas through a serie of 8 cases operated at the department of neurosurgery at Mohammed VI medical university hospital, Marrakesh. From January 2002 to December 2015. There were 3 male and 5 female patients (mean age, 46.75 years). Cervico-occipital pain (100%) and motor deficit (100%) were the most common presenting symptoms. MRI was the most appropriate diagnostic tool in visualizing tumors of this region. All operations were performed by the posterior approach and gross total resection was achieved in 7 cases. Surgical mortality was 20%. 3 other patients had complications like CSF leak (25%), meningitis (12,5%) and transient worsening of neurological deficit (12.5%) but made neurological recovery later. Foramen magnum meningiomas have long been regarded as difficult lesions both in terms of diagnosis and management. However, with the availability of MR imaging, newer surgical techniques and skull base exposures, the excision of these lesions is becoming easier and safer.

Penetrating head trauma (PHT) include all open head injuries with foreign object in the brain. Although less common than closed head trauma, penetrating head trauma carry a worse prognosis. We received three unusual cases of penetrating head injuries whose prognosis was different according to clinical presentation and initial management of the patient. Treatment of penetrating head trauma aims at controlling bleeding, controlling intracranial pressure and preventing infections. Despite the efforts made by national authorities as well as the adequate management in hospitals, penetrating head injuries are still frequent with significant mortality and morbidity.

Cerebral hydatid disease is very rare, representing only 2% of all cerebral space occupying lesions even in the countries where the disease is endemic. Intracranial hydatid cysts are more common in children and occur more frequently in the supratentorial space. The aim of this paper is to describe the characteristic features of computed tomography (CT) and magnetic resonance imaging (MRI), and to determine the clinical presentation and surgical outcome of cerebral hydatid disease. A 7-year-old girl was admitted to the emergency department because of an epileptic attack. On radiological examination a round, cystic lesion appeared in the parietal lobe and caused shift of the midline structures. The cyst was successfully removed using the dowling technique. The postoperative period was uneventful and seizures were not seen during follow up. Hydatid cyst of the brain presents clinically as intracranial space occupying lesion and is more common in children, it is well demonstrated by CT and MR examinations, and Surgery is the treatment option with affordable morbidity and low mortality.

INTRODUCTION: Spontaneous intracranial hypotension is an infrequent cause of secondary headache due to cerebrospinal fluid (CSF) hypovolemia. OBJECTIVE: To describe a case of headache revealing spontaneous intracranial hypotension complicated by subdural hematoma following lumbar puncture. OBSERVATION: A 34-year-old man presented with acute postural headache. The first cerebral computed tomography scan was normal. Lumbar puncture showed hyperproteinorachy at 2 g/L with six lymphocytic cells. The headache became very intense. At admission, clinical examination was normal. Ophthalmological examination did not show any abnormalities. Encephalic magnetic resonance imaging (MRI) showed bilateral subdural hematoma with tonsillar descent simulating Chiari type I malformation. After surgical drainage and symptomatic treatment, the patient was discharged with no recurrence. CONCLUSION: Spontaneous intracranial hypotension is associated with simple clinical presentation, orthostatic headache, and characteristic MRI findings. Misdiagnosed, it leads to unnecessary procedures.

PURPOSE: Authors report their experience of a pediatric brain stem abscess with a literature review. METHODS: A 2.5-year-old girl first displayed bacterial otitis 3 months before admission. Diagnosis of brain stem abscess was delayed, despite plethoric neurological signs. She complained of right hemiparesis, headache, squint, dysphagia, and false way inhalation pneumopathy. Brain magnetic resonance imaging revealed presence of an abscess in the pons, prompting for a microsurgical pus aspiration. Postoperative course was regular with a total neurological recovery. Clinical and radiological screening showed progressive regression of the pontine lesion after 4 months, despite persistence of a mild contrast enhancement. Present case is the 18th pediatric brain stem abscess reported in literature. RESULTS: Mean age of occurrence is 8.1 ± 4 years (range 0.75-16) without gender predominance. High morbidity is typical and essentially involves motor functions. The most common clinical signs are raised intracranial pressure, motor limbs deficit, and cranial nerve palsies. Fever was found in 10 out of 18 cases (56%). Three patients received conservative medical treatment. Three patients underwent stereotactic aspiration and 12 others underwent microsurgical aspiration or excision. No mortality was reported since the eighties. However, morbidity is still high. CONCLUSION: High clinical index of suspicion is necessary to improve functional outcome. Stereotactic-guided or microsurgical aspiration are still good therapeutic options. The rarity of pediatric brain stem abscesses and the need of optimal management make this case-based update very peculiar.

BACKGROUND CONTEXT: The risk of stroke because of carotid retraction during an anterior cervical spine surgery as well as the risk of bleeding complications after an anterior cervical corpectomy under deep anticoagulation and antiplatelet therapy is a surgical issue poorly addressed in the literature. PURPOSE: To describe the feasibility and safety of a simultaneous carotid endarterectomy and anterior corpectomy and fusion under deep anticoagulation in a patient with a cervical spinal cord compression and a severe carotid artery stenosis. STUDY DESIGN: Case report. METHODS: The authors describe the case of a 79-year-old man who had a 1-month history of progressive pain in the neck and left arm, associated with progressive weakness in the left arm and leg. He also presented a history of coronaropathy and bilateral severe carotid stenosis for which he was receiving a regimen of antiplatelet therapy. RESULTS: The cervical magnetic resonance imaging demonstrated a C4-C5 disc herniation migrating down to C5. His condition worsened rapidly during hospitalization prompting a rapid decompression. Given the necessity of a C5 corpectomy and the risk of stroke during anterior cervical spine surgery, it was therefore decided to undertake the surgical procedure under efficient anticoagulant and antiplatelet therapy. A combined endarterectomy and spinal decompression and fusion were then performed. The postoperative course was uneventful, and the patient recovered neurologically. CONCLUSIONS: This case suggests that such a combined carotid endarterectomy and cervical corpectomy with fusion under anticoagulant and antiplatelet therapy is feasible. However, even if the unique clinical presentation of our patient led us to undertake such a surgical strategy, therapeutic decision in patients presenting with both severe carotid stenosis and cervical spinal cord compression should rely on a case-by-case analysis.

BACKGROUND: Cerebral mucormycosis without rhino-orbital or systemic involvement is an extremely rare condition mostly associated with parenteral drug abuse. CASE DESCRIPTION: We report the case of a 42-year-old woman who presented with hemiparesis of the left side and altered mental status. Neuroradiologic workup demonstrated an inflammatory lesion involving the right basal ganglia. Proton magnetic resonance spectroscopy demonstrated features consistent with a pyogenic abscess. Computed tomography-guided stereotactic biopsy led to the diagnosis of cerebral mucormycosis. Parenteral AMB-L treatment was conducted, but the patient worsened clinically, presenting with a complete hemiplegia, and cerebral magnetic resonance imaging (MRI) scans demonstrated a voluminous abscess formation. Then, under stereotactic guidance, a surgical endoscopic debridement of the abscess cavity associated with the placement of an Ommaya reservoir was performed. Systemic and intralesional treatment with AmB associated with an adjunctive immune therapy was conducted. At 3-year follow-up, the patient had recovered partially from her left hemiplegia, allowing her to walk without help, and cerebral MRI scans showed complete resorption of the abscess. CONCLUSION: Our good results suggest that surgical endoscopic debridement associated with intravenous and intracavitary antifungal therapy might be valuable in treating voluminous deep-seated mucormycotic lesions.

BACKGROUND: There are no randomized controlled trials comparing TC, PTGC, and MVD for idiopathic TN at a single institution using quality criteria. The aim of the study was to assess the long-term outcome (efficiency and morbidity) of treated patients with one of these techniques in the same institution. METHODS: The authors present a retrospective study of 165 consecutive patients from 1983 to 2004. The inclusion criteria were drug-resistant idiopathic TN and intolerance to medical treatment. Three groups were set up according to the techniques used: group I (n = 73), treated by TC; group II (n = 41), treated by PTGC; group III (n = 51), treated by MVD. The main judgment criterion was pain relief. The second judgment criterion was morbidity. chi(2) or Fisher exact test, Kaplan-Meier, and log-rank were used for statistical analysis. RESULTS: The 3 groups were homogeneous according to age, duration of evolution, and pain topography. Concerning sex, groups I and II were different (women, 58%; vs. 37%; P = .021). The immediate efficiency for the 3 groups was, respectively, 96%, 94%, and 95% (NS). At 6 years follow-up, 70%, 77%, and 72% of the patients, respectively, remained pain-free (NS). As determined by the Kaplan-Meier survival curve, there was no difference between the 3 groups (log-rank, P = .867). Hypoesthesia was more frequent for PTGC (89%). CONCLUSIONS: In our study, we did not find MVD to be more effective than the other techniques. However, it had the lowest long-term complication rate, which is a strong argument in choosing this technique as the initial procedure for young and healthy patients. Percutaneous techniques, however, are still recommended in specific circumstances.
