Pelvic lipomatosis with ureteral encasement and recurrent thrombophlebitis.

Multiple complications occurred in a patient with severe pelvic lipomatosis and recurrent superficial thrombophlebitis. Distal ureteral and rectal encasement by lipomatous infiltration caused obstructive uropathy and rectal deformity without substantial compromise of renal or gastrointestinal function. Clinical evidence suggests an association between pelvic lipomatosis and recurrent superficial thrombophlebitis.
