[Intramedullary schwannoma. A case report].
The intramedullary localization of schwannoma is rare, corresponding to 0.3% of all intraspinal tumors. We report a case of intramedullary schwannoma without symptoms suggestive of neurofibromatosis. This patient presented with symptoms of spinal compression. Total removal of the tumor was achieved. The literature is reviewed about of this rare localization of schwannoma.

[Postoperative infection following craniotomy in adults].
OBJECTIVE: The aim of this study was to determine the risk factors for postoperative infection after craniotomy, a threat for the vital prognosis, in order to define specific prevention measures. METHOD AND PATIENTS: An open prospective study was made on all adult patients undergoing craniotomy and followed 30 days postoperatively. The infections were defined according to CDCA criteria. The parameters studied were: age, sex, ASA and Glasgow scores, neurosurgical history, the type, the moment and the surface of shaving, antibioprophylaxis, and the type and duration of surgery as well as its emergency level. RESULTS: One hundred and seventy patients were included. Thirty presented with an infection (17.6%), nine with a skull infection, 13 with meningitis, three with empyema, and two with osteitis. The risk factors identified thanks to a univariate analysis were the emergency level of surgery (P < 0.01), duration of surgery >200 min, and duration of stay in ICU >72 h (P < 0.02).

[Lumbar intradural hydatid cyst. Case report].
Hydatid disease is a serious public health problem in developing countries. Cerebrospinal localizations account for 1% of all cases of hydatid disease. The spino-radicular form is exceptional. We report a case of a 25-year-old women with cauda equina. Thoraco-lumbar MRI has showed an intradural process extending from L3 to L5, a low-intensity signal on T1 weighted images and a high-intensity signal on T2 weighted images, which were not enhanced after gadolinium injection. There was no vertebral involvement. After L3 L4 and L5 laminotomy and opening of the dura-matter, multiple vesicles were found scattered among the roots, with no adhesion to meninges or nervous structures. Total extirpation was easy. The outcome was marked by recovery of the motor deficit and sphincter disorders. This localization is serious but its prognosis is excellent if the diagnosis is made early enough to prevent cyst rupture and to allow total resection.

[Cerebellar schistomiasis. A case report].
Schistomiasis or bilharziosis remains an endemic parasitic disease in many countries world wide. Urogenital, intestinal and hepatic symptoms are common. The brain is exceptionally involved and very few cases have been described in the literature. We report the case of a 35-Year-old male with a history of hematuria and bladder disorders, who developed signs of intracranial hypertension and a cerebellar syndrome over a period of one Month. Brain MRI disclosed a cerebellar lesion and a pelvic CT scan revealed a bladder tumor. Treatment consisted in a ventriculo-peritoneal shunt and corticosteroid therapy. Cystoscopy was performed for total resection of the bladder lesion. Histopathology confirmed the diagnosis of schistomiasis. Surgery was also performed to approach the cerebellar lesion. Histopathology showed the inflammatory nature of the lesion. The patient was given an antiparasitic treatment. Clinical and radiological radiological manifestations regressed.

[Intramedullary tuberculomas. Five cases].
Tuberculosis of the central nervous system is uncommon. The intramedullary localization is exceptional. We report five cases of intramedullary tuberculosis observed in four women and one man with a mean age of 43 years. Two patients had a prior history of tuberculosis. Spinal cord compression was found clinically in all cases. The spinal MRI visualized the tuberculoma in all patients; two had a double tumor. Complete removal of the tuberculoma was possible in only one patient. Outcome was stationary for four patients.

[Epidermoid cyst of the cerebellopontine angle. A surgical series of 10 cases and review of the literature].
Epidermoid cyst or cholesteastoma is a congenital slow growing lesion. It usually arises in the paramedian cisterns of the posterior fossa. Its incidence varies between 0.2 and 1% of all intracranial tumors. The cerebello-pontine angle (CPA) is the most common localization. Our study reports 10 observations of CPA epidermoid cysts, treated in our department between 1989 and 1999. The age of our patients ranged from 20 to 45 years, with male predominance. The patients were admitted with symptoms of cerebello-pontine angle syndrome or signs of posterior fossa tumor. CT-scan was performed in all cases and MRI was performed in 5 patients. The audiometric explorations only provided an orienting contribution. Treatment was exclusively surgical. The retro-sigmoid approach was used in 6 cases, the sub-occipital in 30% and a subtemporal approach in one case. Total resection of the epidermoid cysts was accomplished in 4 cases, and subtotal resection in 4 cases. Two patients underwent partial resection and underwent a revision procedure. The histological examination showed an epidermoid cyst in all cases. The clinical course was controlled in 6 patients: 4 patients recovered and became symptom free. A persisting neurologic deficit was observed in two cases (hearing loss, dysphonia); 4 patients were lost to follow-up. Epidermoid cyst is a benign tumor. Total resection is the ideal treatment, but we have to be aware, taking into consideration the adherence of the tumor to neurovascular structures, of the risks at attempting total resection.

[Acute subdural hematoma of the posterior fossa in the child. Case report].
Acute subdural hematoma (ASDH) of the posterior fossa is very rare in childhood. It represent 0.52% of all subdural hematomas. We report a case of post-traumatic acute subdural hematoma of the posterior fossa in a 4-year-old child who was drowsy, without a neurologic defect. The CT scan revealed a simple ASDH, with a good recovery after surgical treatment. The literature is reviewed, clinical and therapeutic aspects are discussed.

[Subperiosteal hematoma of the orbit associated with subfrontal extradural hematoma].
Subperosteal hematoma is rarely associated with extradural hematoma and orbital roof fracture. We report a case observed in a 16-year-old boy who developed exophthalmos, diplopia and visual loss after blunt head trauma. Computed tomography demonstrated the subperiosteal hematoma associated with a thin extradural hematoma and an orbital roof fracture. The hematomas were removed during the same procedure via fronto-orbito craniotomy. Surgery led to complete recovery without functional sequelae. We stress the importance of early diagnosis and treatment of post-traumatic exophthalmos.

[Suboccipital tuberculosis: a case report].
Suboccipital tuberculosis is an uncommon localization of Pott's disease. The gravity results from the neurological and life threatening risk. We report a case of suboccipital tuberculosis in a 22-year woman who survived. She was given an anti-tuberculosis antibiotic regimen due to pulmonary and pericardal involvement. The patient interrupted her treatment after four months and was admitted six months later for torticolis and spastic tetraplegia without sphincter disorders. Standard x-rays and MRI of the head confirmed suboccipital Pott's disease. Transcranial evacuation was performed and the patient was again given anti-tuberculosis antibiotics. The clinical course was favorable with definitive recovery 45 days later. The patient continued the antibiotic regimen for nine months. An orthopedic supporting device was worn for nine months. The diagnosis of suboccipital tuberculosis can be confirmed on MRI. Appropriate treatment is a subject of debate between exclusive orthopedic or combined orthopedic and surgical treatment. Prognosis depends on the neurological deficit, early diagnosis and prompt treatment.

[Sphenotemporal aneurysmal bone cyst. A new case and review of the literature].
Aneurysmal bone cysts (ABC) are benign tumors of the bones, formed by multiple cysts filled with blood and eroding the bone. They are rarely located at the skull. We report a case of a right temporal ABC in a 5-year-old girl. On admission, the physical examination showed a tough and fixed tumor, with no inflammatory signs nor vascular characteristics. The neurological examination was normal. Imaging studies showed an heterogeneous extracerebral mass, eroding the temporal bone and the greater wing of the sphenoid bone. The treatment consisted in an extensive tumor resection, associated with reconstructive surgery. The outcome was uneventful (follow-up 27 months). We underline the pathogenetic, diagnostic and therapeutic features of this condition.

[Multiple cerebral hydatic cysts of cardiac origin. A case report].
The hydatic cyst is a pathology observed in developing countries. Multiple cerebral localizations with a cardiac origin are exceptional and are sometimes diagnosed only after onset of complications. We present the case of a 22-year-old male student: the diagnosis of multiple cerebral hydatic cysts caused by rupture of a cardiac hydatic cyst was established after an episode of ischemia of the limbs with cerebral hemorrhage induced by heparin. One year later, the clinical situation consisted in intracranial hypertension, hemiplegia and convulsive seizures. We observed no cardiac symptoms. The brain CT showed 9 hydatic cysts and echocardiography showed a myxomatous cystic tumor. Abdominal CT detected renal and splenic hydatic cysts. The patient underwent total ablation of the cerebral and abdominal cysts and made a full recovery. After surgical removal of the cardiac cyst, the patient has been lost to follow-up. Cerebral hydatidosis of cardiac origin is highly exceptional and, due to nonspecific symptomatology, may go undiagnosed. In general, prognosis is good in case of a cerebral localization but the cardiac localization is associated with high mortality.

[Spinal cord compression disclosing rib hydatidosis].
The authors report an exceptional case of spinal compression following an isolate rib hydatidosis. The CT scan has suspected the diagnosis. The authors recall the anatomoclinic features and specify the radiologic aspects of the osseous hydatidosis, especially the rib's localization which is very rare. MR imaging in addition of its diagnosis role showing a very evocative cyst images, is the exam of choice in order to appreciate the disease's extent and the degree of medular sufferance.
