Anatomic and pathologic spectrum of pituitary infundibulum lesions

AJR Am J Roentgenol. 2007 Mar;188(3):W223-32. doi: 10.2214/AJR.05.2027.


Objective: The pathologic spectrum of pituitary infundibulum disease is diverse. We reviewed 65 infundibular lesions in 44 adult and 21 pediatric patients and summarized their imaging features and clinical presentation.

Conclusion: The spectrum of pathology involving the pituitary infundibulum is broad yet distinct from other pathology in the sella and parasellar region. Pituitary stalk lesions can be grouped into three categories: congenital and developmental, inflammatory and infectious, and neoplastic. Knowledge of the imaging appearance of diseases specific to adults and to children is important for accurate diagnosis and treatment.
