Primary pituitary tubercular abscess mimicking as pituitary adenoma

Tubercular abscess of the pituitary fossa is rare and may lead to diagnostic uncertainty in a patient with absence of tuberculosis elsewhere in the body. We present a rare case report of a young lady who presented with sellar and suprasellar cystic mass. She was diagnosed as a case of pituitary macroadenoma and was intraoperatively found to harbor pus in the lesion. She did not have any symptoms of infection. The case underlines the importance of considering such a possibility in the differential diagnosis of cystic sellar lesions and further diagnostic tests should be done for confirmation and treatment of this rare and potential life threatening illness.
