Myocardial Hydatid Cyst : An Uncommon Complication of Echinococcal Infection

abstract: A 27 –years-old man presented with malaise, fatigue and atypical chest pain. Transthoracic echocardiography was performed and revealed a single large and well defined intra-myocardial cystic mass in the inter-ventricular septum. The cystic mass was thin-walled and contained some small daughter cyst. Although the echocardiographic diagnosis was straightforward, serologic test (Hydatid cyst antibody) with Eliza was performed which was positive for echinococcal infection. Other works up showed no involvement of other organ system. Albendazol was started for him and he referred to cardiac surgeon for resection of cystic mass but the patient refuse for operation.
