Compression of Left Portal Vein By Giant Hydatid Cyst Extending from the Caudate Lobe to the Foramen of Winslow

Hydatid disease may affect any organ or tissue, but the most involved organ is the liver. Despite the fact that it is an asymptomatic disease in most patients, about one-third of patients will have a complication. The most common complications of hydatid disease are cystobiliary communications, superinfection, cyst rupture, and mass effect induced complications. Primary aim of this study is to present this case study, 27 years old female patient, regarding a hydatid cyst originating from caudate lobe of the liver, extending to the foremen of Winslow and resulting in pressure on the left portal vein with heterogeneous liver parenchyma seen on computed tomography; as extensive, causing abdominal pain and treated before causing portal venous thrombosis or portal hypertension. The patient underwent cholecystectomy, pericystectomy and received preoperative and postoperative albendazole treatment. In the contrast enhanced computed tomography taken five months after the surgery, it was observed that the heterogeneity in the liver parenchyma completely resolved. After reviewing the literature, there were no studies showing early treatment of such cases before complications occurred.
