Isolated sellar tuberculoma presenting with panhypopituitarism: clinical, diagnostic considerations and literature review.

Tuberculosis, a common cause for chronic intracranial infections can mimic varied intracranial pathologies including tumours. Pituitary tuberculomas are rare lesions and are often diagnosed pre-operatively as pituitary tumours. We report a case of a 31-year-old lady with a sellar-suprasellar lesion who presented with panhypopituitarism. The patient underwent a trans-nasal, trans-sphenoidal surgical decompression of the lesion. Histopathology revealed a tuberculous lesion in the pituitary. The characteristic radiological features of sellar tuberculomas are discussed along with a review of literature. Atypical sellar radiology in the presence of a thickened pituitary stalk could point to pathology other than pituitary adenoma, possibly a chronic inflammatory condition like tuberculoma.
