Granulomatous hypophysitis: rare disease with challenging diagnosis

Abstract

Abstract: Granulomatous hypophysitis is rare pathology that mimics pituitary adenoma. Diagnosis is only confirmed by histopathology examination. Trans-sphenoidal surgery is considered diagnostic when descent tissue specimen is obtained and therapeutic by decompressing optic pathway and the sella. Pathological findings always reveal granulomatous areas, multinucleated giant cells, plasma cells, and lymphocytes.
