Torsion of an intraperitoneal undescended seminomatous testicular tumour.

A 42-year-old man presented acutely with lower abdominal peritonism and a medical history of a right orchidopexy as a child. Further history from his mother revealed that during the procedure the left testicle could not be found. In view of his unusual history and the nature of the pain a CT scan was performed demonstrating a 10×8 cm solid mass above the bladder.
