[Diagnosis and treatment of extensive vertebral tuberculosis].

Tuberculous spondylodiscitis called Pott's disease is the most common presentation of vertebral tuberculosis. Atypical presentation is rare and its diagnosis also difficult. We report a retrospective analysis of 7 immunocompetent patients treated for extensive vertebral tuberculosis. Five men and two women, between 5 and 39 Years. The median age was 24 Years. Clinical features were incomplete tetraplegia (4 cases), complete paraplegia (1 case) incomplete paraplegia (1 cases), and lumbocruralgia (1 case). Spinal X-ray revealed spondylodiscitis. Both CT Scan and MRI are very useful to determine the extent of the lesions. Bacteriological and histological diagnosis can be deficient. For this reason, we insist on a the contribution of antituberculous treatment to diagnosis. But the appearance of drug-resistance can limit the role of antituberculous chemotherapy in achieving diagnosis.

[Thoracic spinal stenosis. Clinical and surgical management. Study of 5 cases observed in the Abidjan department of Neurosurgery].

BACKGROUND: Spinal cord compression resulting from thoracic spinal stenosis is relatively frequent in Japan but rare in Europe and little know in Africa. OBJECTIVE: We report five cases of thoracic myelopathy caused by thoracic stenosis diagnosed in black African people. METHODS: This was a retrospective observational study of patients treated in the Abidjan department of Neurosurgery from 01.01.1996 to 31.12.1998. The spinal cord compression resulting from thoracic spinal stenosis was confirmed by myelography or myeloscan. The Japanese orthopaedic association (JOA) score was used to evaluate patient outcome. RESULTS: All of these patients were black Africans. The four men and one woman were aged 55, 47, 53, 52, and 60 years. The clinical presentation of thoracic spinal cord compression was confirmed by myelography in five patients and by myeloscan in four. These investigations were useful for guiding surgical treatment. Outcome was favorable in all cases. CONCLUSION: Signs of thoracic spinal cord compression in adults should suggest the diagnosis of thoracic spinal stenosis.

[Spondylodiscitis due to Histoplasma duboisii. Report of two cases and review of the literature].

We report two cases of African histoplasmosis caused by Histoplasma duboisii located in the spine, on two Malian adults aged 40 and 47 years respectively. Clinical signs consisted of dorsal spinal syndrome in both cases and a paraplegia in one case. Radiography and CT scan revealed a spondylodiscitis without any bone reconstruction in both cases and a prevertebral abscess in one case. Diagnosis was confirmed by mycological and pathological examinations of surgical specimen which revealed Histoplasma duboisii fungus. Medical treatment, after surgical repair, consisted in ketoconazola with positive results after 12 months. This localisation is rare. It raises diagnosis problems with tuberculous spondylodiscitis because of their radio-clinical resemblance.

[Medullary compression by Burkitt lymphoma. Analysis of 7 cases].

OBJECTIVES: Burkitt's lymphoma is one of the possible cause of spinal cord compression. We defined the surgical approach in this rare localization of Burkitt's lymphoma. PATIENTS AND METHODS: We report 7 cases of spinal cord compression secondary to Burkitt's lymphoma treated at the Yopougon University Hospital from October 1990 to October 1994. RESULTS: Mean age of the patients was 15.4 years, range 8 to 28 years. Five of the 7 patients were children. Surgery was both a diagnostic and therapeutic emergency in this rare but serious localization of Burkitt's disease, which remains highly chemosensitive. CONCLUSION: Surgical management is warranted if Burkitt's lymphoma is revealed by spinal cord compression or if there is a primary spinal epidural localization.

[Dural metastasis of prostatic adenocarcinoma presenting as acute intracranial subdural hematoma: a case report].

Intracranial malignant metastatic dissemination usually is seen as a unique nodular formation enhanced after intravenous injection of contrast medium. Forms mimicking meningioma or subdural hematoma have been described. We report a case of dural metastasis from an adenocarcinoma of the prostate in a 60-year-old man. The CT image suggested acute subdural hematoma.

[Neurosurgical complications of purulent meningitis in the tropical zone].

Our retrospective study concerned 35 cases of surgical complications related to bacterial meningitis in 16 adults and 19 children. The mean age was 28 years for adults (15-56 years), and 6 months for children (1-12 months). Portal of entry for meningitis was found in 12 cases (35%): 8 sinusitis and 4 otitis. Delay to appearance of complications was 4.5 days, and to diagnosis confirmation 9 days with CT scan (17 cases), and transfontanellar ultrasonography (19 cases). The complications were: hydrocephalus, 19 cases (54%), brain empyemas, 7 cases (20%), abscesses, 10 cases (28.5%), ventriculitis, 2 cases (6%). Twenty-two bacteria were isolated from the CSF: Streptococcus pneumoniae (15 cases), Haemophilus influenzae (5 cases), Neisseria meningitidis (1 case), and Escherichia coli (1 case). Fourteen patients underwent neurosurgical treatment based on aspiration in case of suppuration and external drainage in case of hydrocephalus. The associated medical treatment was antibiotics combining third-generation cephalosporins, fluoroquinolone, and metronidazol, with a mean duration of 12 days. Recovery rate was 89%, letality 11%, and after effect rate were 33%. Our results confirm the low frequency of neurosurgical complications related to bacterial meningitis, but it emphasizes the role of an early CT-scan for diagnosis and prognosis.

Spinal cord compression resulting from Burkitt's lymphoma in children.

We report seven cases of spinal cord compression resulting from Burkitt lymphoma in boys aged 15 years and below. This became manifest clinically as acute or rapidly progressive spinal cord compression. All the patients showed total paraplegia with a sensory loss at thoracic level and sphincter disturbances. Four patients were operated on, the operation permitting exeresis of an epidural tumor. In three cases surgery was followed by chemotherapy. One patient was treated exclusively with chemotherapy. Owing to the effectiveness of chemotherapy, surgery should be considered only in cases of rapid deterioration or for diagnostic purposes.

[Medicosurgical approach of intracranial pyogenic bacterial suppurations in Abidjan. Analysis of 26 clinical cases].

We report 19 cases of cerebral abscesses and 7 cases of subdural empyemas in 5 months to 63 years old patients (1983-1991). Bacteriological agents in 13 cases are. 6 Staphylococcus aureus, 5 negative Gram bacilli, 1 Streptococcus, 1 pneumococcus. Predisposing factors are sepsis of adjacent organs (42%), septicemia (19%), post-traumatic and post-surgical infections (19%). Lethality is 11.5%. The authors stress the interest of CT scan and bacteriological studies now available in Abidjan with the creation of the Department of Neurosurgery.

[Pituitary abscess, treated by medication].

Pituitary abscesses are rare. The case reported here concerns a 28-year old African. Gradual development of diplopia over 6 months was the first clinical manifestation. Three months later this development had reached a more severe and infectious context, with complete right ophthalmoplegia, meningitis and coma (GCS = 9). CT scan showed an image in favour of a pituitary abscess with suprasellar extension, associated with thrombophlebitis of the cavernous sinus. An antibiotic therapy consisting of cefotaxime and metronidazole administered for 1 month, and netilmicin for 15 days succeeded in controlling the infectious syndrome. This resulted in cure of visual disorders, reduction in size of the CT scan image and reconstruction of the pituitary sella which had been destroyed. The diagnosis of pituitary abscess should be made when confronted with an infectious syndrome (unexplained fever, repeated meningitis). CT does not recognize the nature of the hypophyseal mass it shows: necrosis of a pituitary adenoma, giant aneurysm or craniopharyngioma may mimic local infection. Surgery confirms the diagnosis and is regarded as the best treatment. The patient's life is threatened when meningitis is present, and the functional prognosis is poor when recovery from visual disorders is compromised due to late diagnosis. In this paper a comparative analysis of the clinical course of the disease and therapeutic data in our patient is presented and compared with other reported cases.

[Tuberculous abscess of the cerebellum].

Cerebral tuberculous abscess is exceptional. We report on the case of a H.I.V. positive 29 year-old man suffering from high intracranial pressure together with a cerebellar syndrome. The CT scan revealed a voluminous abscess of the left cerebellar hemisphere. Anatomical and pathological examination of the extracted mass showed a tuberculous abscess. 16 months after surgery and antituberculous treatment, the patient's symptoms have disappeared and he has resumed his professional activities. Though controversial, a pathogenic continuum between a tuberculoma and a tuberculous abscess may be assumed to exist. The A.I.D.S. pandemic reactivates the tuberculous foci, increases the risks of contagion reduced the effectiveness of treatment, and justifies a systematic search for the bacillus of Koch, after puncture, in any cerebral abscess.

Colloid cyst of the fourth ventricle: diagnostic problems and pathogenic considerations.

The authors report the case history of a patient with a colloid cyst of the 4th ventricle. The clinical history of slow intracranial hypertension, homogeneous hyperdensity with contrast enhancement on computed tomographic, scan, and the gelatinous aspect of the cyst at surgery are characteristic of colloid cysts. The diagnosis was made, however, only at the time of histological examination. A common neuroepithelial origin with 3rd ventricle cysts would be explained by similar embryological developments of the prosencephalic and the rhombencephalic roofs.
