interventricular septum hydatid cyst: successful seven-year follow up- case report.

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. histo-pathological 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 echino-coccosis should be considered in differential diagnosis.
