Unusually located primary hydatid cysts

Abstract

The hydatid disease caused by Echinococcus granulosus is an endemic parasitic disease affecting several Mediterranean countries. Echinococcal cysts are mostly located in the liver and the lung, but the disease can be detected anywhere in the body. In this study, we present uncommon extrahepatic localizations of primary hydatid disease. Patients who were operated on for hydatid disease or cystic lesions, which were later diagnosed as hydatid disease, between 2004 and 2010 were retrieved retrospectively. Patients with lesions localized outside the liver and the lung were enrolled in the study. Eight patients with extrahepatic primary hydatid disease were treated surgically at our clinic. The cysts were located in the scapular region, spleen, pancreas, lumbosacral region and gluteal muscle. Surgical techniques were partial or total cystectomy with or without tube drainage. Splenectomy was performed for splenic hydatid disease and partial pericystectomy, Roux-en-Y cystojejunostomy, cholecystectomy and T-tube drainage for pancreatic hydatid disease. There were no complications or mortality in the postoperative period. Hydatid cyst should be considered in the differential diagnosis of cystic lesions, especially in endemic areas. Surgical technique should be planned according to the location of the cyst.

There were no direct interactions with subjects and knowledge gained would not impact subject’s clinical care, thus, informed consent was not obtained.
