A PSA for Radiologists: Pictorial Review of Incidentalomas on Prostate Magnetic Resonance Imaging

Can Assoc Radiol J. 2019 May;70(2):134-146. doi: 10.1016/j.carj.2018.09.005. Epub 2019 Mar 8.

Abstract

Multiparametric magnetic resonance imaging (MRI) of the prostate is a powerful and increasingly utilized imaging study for the diagnosis, staging, and surveillance of prostate cancer. With greater adoption by clinicians, it is becoming more common for incidental findings to be first detected on prostate MRI. Inadequate description of clinically significant findings may not prompt appropriate patient management, while over-reporting of indolent findings comes at increased patient anxiety, cost of workup, and iatrogenic risk. This review article aims to improve awareness, review pathophysiology, and present key imaging features of incidental findings seen on prostate MRI, ranging from common to rare and from benign to clinically significant.
