CASE-REPORT - PSEUDOTUMORAL PELVIC RETROPERITONEAL FIBROSIS ASSOCIATED WITH ORBITAL FIBROSIS

We report the case of a man with bilateral orbital fibrous pseudotumou rs and a large pelvic mass which was initially thought to be malignant . Sonographically guided transrectal core biopsies showed it to be a f ibrotic retroperitoneal pseudotumour. The mass decreased after steroid therapy. The computed tomography and magnetic resonance imaging featu res of this unusual form of pelvic fibrosis as well as the association with heterotopic fibrosis are discussed.
