Seven weeks after a generalized cerebral seizure a 27-year-old woman from Ghana developed nausea, vomiting and weight loss, gradually increasing over two weeks. Cranial computed tomography revealed several hyperdense formations with extensive associated oedema and a midline shift. Among extensive biochemical tests only a raised erythrocyte sedimentation rate of 24/50 mm and leukopenia of 2,600/microliters (with normal differential count) were notable. Diagnostic laparotomy was performed because of sonographic and computed tomographic evidence of enlarged abdominal lymph nodes. Histological examination of representative lymph nodes and of tiny nodules deposited on the peritoneum revealed caseous granulomatous inflammation. Mycobacterium tuberculosis was cultured from these specimens. Antituberculosis treatment was started with 0.3 g/d isoniazid, 0.6 g/d rifampicin, 2 g/d pyrazinamide and 1 g/d streptomycin, plus dexamethasone, 4 mg four times daily. After eight weeks treatment an intracerebral focus, removed to exclude neoplasm, proved histologically to be a tuberculoma. Only after four months was it possible to reduce the glucocorticoid dosage to prednisone, 20 mg/d. The antituberculosis treatment was continued for 18 months, with only isoniazid and rifampicin taken during the last 14 months. Final clinical and biochemical examinations were unremarkable. Computed tomography demonstrated regression of the abdominal lymph nodes and the cerebral foci. The patient was without any symptoms.
