ABSTRACT

Tuberculous Brain Abscess (TBA) is a rare manifestation of CNS tuberculosis. Only a few cases have been reported in literature. A twenty six year old male presented with high grade fever, throbbing headache and altered sensorium. Examination revealed neck stiffness and papilloedema. His chest X-ray showed evidence of healed pulmonary tuberculosis. MRI Brain showed a well circumscribed hyper intense lesion in the left parietal region with perilesional edema and mass effects. Stereotactic aspiration of the abscess yielded frank creamy pus. PCR for Mycobacterium tuberculosis MPB 64 was positive which confirmed the lesion to be of tuberculous etiology. Patient responded well to four-drug regimen of antitubercular treatment.
