[Pelvic lipomatosis. A case with ureteral and venous obstruction].

The authors report a case of pelvic lipomatosis in a 62 year old man associated with venous obstruction (third case reported in the literature), diagnosed after bilateral ureteric obstruction, and review of the literature on this subject. The diagnosis was suggested by the radiological triad of hyperlucency of the pelvis on plain abdominal X-ray, "hot air balloon" appearance of the bladder on IVU and a rigid and ascended rectosigmoid on barium enema, and was confirmed by CT and MRI. Treatment combining corticosteroids and urinary tract disinfection was partially effective. A double J ureteric stent resolved the problem of persistent right ureteric obstruction.
