The case report shows a surprising presentation of pulmonary granulomatosis with polyangiitis (GPA) through symptoms of diabetes insipidus (DI) with granulomatous infiltration of the pituitary gland. The pituitary hormonal dysfunction as a result of granulomatosis of the pituitary gland is rare. Several studies have demonstrated that the incidence of the pituitary dysfunction reaches approx. 1 % of the patients with GPA. However it is mostly presented in patients with the disease already diagnosed. The patient described by us had no clinical expressions of GPA in the respiratory tract. He presented with polyuria and polydipsia. It was not until a more detailed examination of these symptoms was performed that a focal lung disease was detected and diagnosed as GPA.
