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.

[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.

[Recurrences of supratentorial meningiomas. Apropos of 17 cases].

17 cases of recurrent meningiomas observed during a 10 years period are reviewed. Meningiomas with a second localisation different from the first were excluded from the study. The tumor recurrence occurred mostly during the first five years after the surgical procedure. One case with femoral and pulmonary metastasis is described. Several factors may play a role in the genesis of the recurrence: age, sex, the tumor localisation, CT scan, the importance of the tumor ablation, the histology. In almost all cases a radiotherapy was carried out after the second surgical procedure. This retrospective study suggests the need for multifactorial prospective analysis with clinical, paraclinical and fundamental factors. Such a study would be useful to precise the natural history of meningiomas.

[Extra-medullary intradural melanotic tumor: apropos of a case of dorsal pigmented neurinoma. Review of the literature].

The authors report a case of pigmented thoracic neuroma (T3) discovered in a 40 year old woman on a routine chest x-ray. This hourglass-shaped extra-dural tumour was investigated by computed tomography, nuclear magnetic resonance imaging and iopamiron myelography. Treatment consisted of complete resection by T2-T3 laminectomy and left T3 foraminotomy. Light and electron microscopy revealed melanin secretion by the Schwann cells. A review of the literature confirms the findings observed in our case in terms of the slow clinical course, the benign nature and the excellent prognosis following complete resection, without the need for any radiotherapy or chemotherapy. The various histogenetic theories of extramedullary intra-dural melanotic tumours are reviewed. The difficulties of the differential diagnosis are discussed.

[Secondary bone cancer in the Ivory Coast. Apropos of 40 cases].

From the statistics dealing with cancer yielded in the Internal Medicine Department, Treichville Hospital, secundary bone cancer appears with a low percentage. The short expectation of life and the reluctance of African patients to report to the hospital must be considered to appreciate these data. Most often, at their admittance, cases show numerous and large metastasises. Bone tumors related to a primitive liver cancer are rare. More often, metastasises in prostate cancer may be observed. They are generally osteocondensing. Breast cancer is, for its frequency, ranking just after it. In one third of the cases, the origine has not been cleared out.
