In 1990, specific antituberculous chemotherapy can cure almost 100 p. cent of patients with pulmonary tuberculosis in France, provided practitioners follow strict therapeutic rules and patients' compliance with treatment is perfect. A single standard treatment is proposed for those patients whose tuberculosis has never previously been treated; it consists of a six months' course of isoniazid (5 mg/kg/day) and rifampicin (10 mg/kg/day); combined with ethambutol (20 mg/kg/day) and pyrazinamide (30 mg/kg/day) during the first two months. This treatment must be administered under regular medical supervision, and it must be prolonged for some time after cure has been obtained. In case of relapse or in some special situations (e.g. pregnant women, HIV positive patients, serofibrinous pleurisy, complex anatomico-clinical forms of the disease) treatment is more difficult, but it should always give favourable results.
A case of lateral sinus thrombosis which occurred after mastoiditis in an 8 year old girl is reported. The elements of clinical diagnosis, the contribution of medical imaging and the medical and surgical management of this scarce but potentially severe affection are discussed.
