Hypothalamic-pituitary sarcoidosis.

ABSTRACT

Patients with sarcoidosis may develop hypopituitarism secondary to granulomatous infiltration of the pituitary and hypothalamus. All degrees of anterior pituitary insufficiency can occur, ranging from selective deficiency to panhypopituitarism; diabetes insipidus occurs frequently. Commonly associated neurologic manifestations are cranial neuropathies, aseptic meningitis, and visual field defects. Although neurologic deficits respond well to corticosteroids, hormonal abnormalities generally persist despite therapy.
