Peritoneal computed tomography: a diagnostic tool for genital oedema in patients on peritoneal dialysis.

A 55-year-old man, who had a medical history of diabetic nephropathy resulting in end-stage renal failure, was receiving continuous ambulatory peritoneal dialysis (CAPD) as renal replacement. He underwent bilateral open inguinal hernioplasty 3 years earlier. He presented with a sudden onset of right scrotal oedema after CAPD. Physical examination showed a non-tender swelling over the right groin and scrotum. An expansile cough impulse could not be elicited and the swelling did not change in size. The nature of the oedema was uncertain after clinical examination. A peritoneal computed tomographic (CT) scan demonstrated the presence of a right indirect inguinal hernia (Fig). A right inguinal hernioplasty was therefore performed. The patient has remained symptomfree over the past 12 months.
