Jpn J Radiol. 2022 Feb;40(2):120-134. doi: 10.1007/s11604-021-01199-1. Epub 2021 Sep 21.


Adrenal pheochromocytoma is not always a simple retroperitoneal tumor but may be part of a more complicated condition. It often has a spectrum of complex and variable imaging features, may present as a collision tumor and composite tumor, and is associated with a variety of clinical syndromes. A comprehensive understanding of the clinical, pathological, and variable imaging manifestations of pheochromocytoma can help radiologists make an accurate diagnosis. This article reviews various special imaging features of pheochromocytoma and pheochromocytoma-related diseases.

Keywords: Clinical syndrome; Computed tomography; Imaging features; Magnetic resonance imaging; Pheochromocytoma.
