Imaging of Non-malignant Conditions of the Prostate and Seminal Vesicles: A Comprehensive Review

Non-malignant conditions of the prostate and seminal vesicles are much more common in imaging practice than prostate cancer. They include benign prostatic hyperplasia, infective and inflammatory prostatitis, prostatic and periprostatic cysts, and benign tumors. The advances in magnetic resonance imaging (MRI) of the prostate gland have dramatically improved the ability to identify these entities, many of them being identified incidentally in patients evaluated for other indications. Good knowledge of these conditions can aid in precise diagnosis and avoid interpretation pitfalls. In this article, we present non-malignant conditions of the prostate gland using several imaging modalities, including transrectal ultrasound, MRI, and computed tomography. We also present the pathological correlation for benign tumors.
