To our knowledge there is no reported case of Total Hip replacement and revision for hydatid disease involving the bony pelvis. Introduction Hydatid disease commonly involves liver and lung. There are many reports on Hydatid disease with the involvement of the musculoskeletal system 1-11 . Involvement of the musculoskeletal system occurs in 1 to 4 of all cases 7 . Hydatid disease is a parasitic infection caused by tapeworm Echinococcus which inhabits in the small intestine of carnivores. The adult worms produce eggs that are released with the faeces and spread in various ways such as through the wind water or flies 6 . After ingestion by the host the embryos migrate through the intestinal wall and are either arrested in the capillary bed of the liver developing into liver cysts or manage to penetrate into systemic circulation thus ending up in remote organs. Due to their physiologic role as capillary filters and their vast capillary volume the liver and lung are most often affected. The brain the muscles or the bones are the more frequently involved distant organs. In this report we present a case of a large recurrent hydatid cyst involving the right ilium and right hip treated with excision of the cyst and Total hip replacement which was functional for 80 months and revision with a Tripolar .
