Thromboses veineuses cérébrales au cours de la méningo-encéphalite tuberculeuse

Cerebral venous thrombosis is a rare disease characterized by its clinical polymorphism and multiplicity of risk factors. Infections represent less than 10% of etiologies. Tuberculosis is not a common etiology, only a few observations are published in the literature. Between January 2005 and March 2015, 61 patients were hospitalized for neuro-meningeal tuberculosis. Among them, three young women had presented one or more cerebral venous sinus thromboses. No clinical feature was observed in these patients; vascular localizations were varied: sagittal sinus (2 cases), lateral sinus (2 cases) and transverse sinus (1 case). With anticoagulant and antituberculosis drugs, the outcome was favorable in all cases. During neuro-meningeal tuberculosis, the existence of consciousness disorders or neurological focal signs is not always the translation of encephalitis, hydrocephalus, tuberculoma or ischemic stroke; cerebral venous sinus thrombosis may be the cause and therefore should be sought.
