Diffuse Meningeal Tuberculosis

A central nervous system infection by Mycobacterium tuberculosis (MT), uncommonly seen in immunocompetent patients, brings a diagnose challenge in the modern medicine. Subdural space involvement of MT may simulate neoplastic or inflammatory diseases, bringing a direct influence in the therapeutics. We present a case report of a tetraparetic middleage woman with an atypical subdural space involvement by MT. Biopsy was done and the standard treatment for central nervous system MT was instituted, with a significant improvement in the motor function. In countries where MTinfection has high prevalence and incidence, an atypical intracranial mass should be always suspected for central nervous system involvement by MT.
