Wegener's granulomatosis presenting as diabetes insipidus

Abstract

Pituitary gland involvement in Wegener's granulomatosis (WG) occurs most commonly in the form of central diabetes insipidus (CDI). However, CDI as a presenting manifestation of WG is very rare. We report two such cases; one of them had multi-organ involvement at presentation, while other developed it during follow-up. CDI was reversible following cytotoxic drug therapy in one of them.
