Diabetes insipidus in sellar-suprasellar tuberculoma.

Tuberculoma involving the sellar and suprasellar region is extremely rare. Sellar region tuberculoma usually presents with endocrinopathy of hypofunction, rarely hyperfunction or normal function of the anterior pituitary. However, sellar-suprasellar tuberculoma presenting with diabetes insipidus (DI) is very rare. We report the case of a 32 year old housewife presenting with DI and secondary amenorrhea, who had a sellar-suprasellar mass on MRI. She underwent a transnasal transsphenoidal surgical removal of the pituitary mass, which was tubercular in nature on histology. She received antitubercular treatment and hormonal replacement therapy. She was well at last follow-up, 3 years after surgery.
