Unexpected discovery of surgical gauze during a robotic radical prostatectomy identified as a capturing lymph node on magnetic resonance

Multiparametric magnetic resonance, plays a crucial role in several steps of the management of prostate cancer. Various factors could alter the interpretation and reduce the accuracy of MR. Among these the group of the retained surgical items, can produce serious implications for the health of patient, as well as medical-legal consequences. Here we report the case of a patient, with a prostate tumor, who performed a mp-MRI of the prostate, where it was reported as collateral finding, compatible thesis with lymphadenopathy. During robotic assisted radical prostatectomy, was found a gauze, which persisted asymptomatic, retained after a previous right inguinal hernioplasty
