Recurrent multiple cardiac hydatidosis.

Cardiac hydatid cyst is an uncommon disease. We report on a woman admitted to our clinic with chest pain and palpitations. The ECG showed anterior ischemia, and coronary anatomy was normal. The diagnosis was: multiple cardiac hydatid cysts, for which she had undergone surgery 4 years earlier for a 5 x 5 hydatid cyst and treated with albendazole. Despite this, there was a recurrence of multiple cysts. Recurrence of intracavitary hydatid cyst is rare, and surgical treatment of multiple, small cysts remains controversial.
