Iliopsoas haemophiliac pseudotumours with bowel fistulation

Two cases of iliopsoas haemophilic pseudotumours are presented. In one pati ent a fistula developed between a pseudotumour and the large bowel. This re sulted in an abscess involving the pseudotumour and adjacent tissues. It re solved after 5 years of therapy involving percutaneous drainage and closure of the fistula. The second patient had a massive pseudotumour that had obs tructed both ureters. Later he suffered a fatal mixed Gram negative septica emia probably related to erosion into the colon.
