Can you trust the Prostate Imaging Reporting and Data System (PI-RADS) in special cases?

Prostate cancer is the second most common cancer and the fifth most common cause of cancer-related death in men worldwide. MRI of the prostate has become an efficient method to detect prostate cancer. PI-RADS guidelines (Prostate Imaging – Reporting and Data System) have been established to standardize MRI of the prostate internationally. We report a case of a prostate lesion defined as likely to be benign on MRI according to PI-RADS version 2 and 2.1 (Assessment category: PI-RADS 2) which was later diagnosed as mucinous prostate adenocarcinoma, a rare variant of prostate adenocarcinoma (0.2 to 0.4 % of acinar adenocarcinoma).
