There was a firm mass in the scrotum with marked tenderness. The patient’s body temperature was 38.0゜C, and blood tests showed increased inflammatory markers. The results of computed tomography and magnetic resonance imaging showed that the enlarged scrotum was filled with gas and there was a mass partially composed of fat inside it.
