Infundibulo-hypophysitis: A Case Diagnosed by Magnetic Resonance Images Over Time, with Literature Review

Infundibulo-hypophysitis is a rare type of autoimmune hypophysitis that involves the pituitary stalk and pituitary. It currently has no clear diagnostic criteria, and is often misdiagnosed as pituitary tumor, leading to unnecessary surgery. Here, we present a 50-year-old woman with in fundibulo-hypophysitis who was diagnosed using multiple magnetic resonance images taken over several months at follow-up. We discuss the course of her disease and her treatment, the imaging features of infundibulo-hypophysitis and similar diseases, and review the relevant literature.
