Two rare central nervous system manifestations of a common disease

Tuberculosis (TB) is an endemic infection caused by Mycobacterium tuberculosis . Various manifestations of the central nervous system (CNS) TB include cerebritis, cerebral abscess, meningitis, tuberculoma, and encephalopathy. Isolated intraventricular tuberculoma and hypertrophic pachymeningitis are two rare presentations of CNS TB infections. Intraventricular tuberculoma is rare, of which third ventricular location is extremely rare and only two cases of third ventricular tuberculoma are reported in the literature. Although leptomeningitis is common, isolated hypertrophic pachymeningitis is an uncommon presentation of CNS TB.
