Interventricular Septum Hydatid Cyst: Successful Seven-Year Follow Up-Case Report

Background: hydatid cyst disease should be considered in differential diagnosis in many doubtful clinical situations as can present with non-specific symptoms especially in the endemic areas. cardiac involvement should be considered in patients with history of previous hydatid cyst disease. cardiac hydatid cysts account for less than 2% of all hydatid diseases. in this report we aimed to present a case of 14-year-old boy with the diagnosis of occlusion of artery of the right lower extremity. surgical exploration of the femoral artery revealed multiple hydatid cysts. echocardiography showed a mobile mixed mass lesion. complete resection of the mass was done from interventricular septum. histopathological examination of the removed tissue revealed a complicated hydatid cyst and complete mass excision was confirmed. in this case a 7 year clinical and serological tests evaluation follow-up after surgical treatment showed no evidence of recurrence. the finding of this case emphasizes that in endemic countries,primary cardiovascular echinococcosis should be considered in differential diagnosis. © 2014,iranian journal of public health. all rights reserved.
