Testicular rupture is a potentially serious sequela of scrotal trauma. Physical examination is often quite limited in these cases. Sonography contributes significantly by directly visualizing the testis and intrascrotal contents. False-positive sonograms can occur, particularly when a hematocele displaces or distorts the testis beyond recognition or when a hematoma is mistaken for a damaged testis. This report describes the ultrasonographic appearance of a hematoma that mimicked a ruptured testis. The testis had actually been removed by the patient himself, who was suffering from a psychiatric disturbance called Munchausen syndrome.
