[Two Cases of Penile Fracture Diagnosed by Magnetic Resonance Imaging].

We report two cases of penile fracture. Case 1 was in a 22-year-old male. He heard a cracking sound during urination and experienced acute penile pain and detumescence. He was admitted to our hospital on that day. Case 2 was in a 52-year-old male. He heard a cracking sound during sexual intercourse and experienced detumescence. He was admitted to our hospital on the next day. In both cases, magnetic resonance imaging (MRI) showed disruption of the tunica albuginea. We performed immediate surgical repair through localized incision. They had no perioperative complications. Several months after surgery, they reported subjectively good erection without penile curvature or pain. We found that MRI is a useful tool for the assessment of location of the tunica rupture and minimization of the surgical incision.
