The coexistence of infundibular pituicytoma and Cushing’s disease due to pituitary adenoma: A case report

Objectives. Pituicytomas are rare, solid, well-circumscribed, low grade (grade I), non-neuroendocrine, and noninfiltrative tumors of the neurohypophysis or infundibulum, which appear in the sellar/suprasellar regions. Herein, we present a case with Cushing’s disease (CD) caused by an ACTH-secreting pituitary adenoma in association with an infundibular pituicytoma.
