Cystic echinococcosis of the heart and brain: a case report.

A very rare case of echinococcus cysts of the heart and brain in a 27-year-old man who worked as a butcher, lived on a farm, and had a dog before disease onset. The initial manifestation of hydatid disease was anaphylactic shock, the etiology of which remained unknown on initial hospitalization. On rehospitalization, the diagnosis of cardiac hydatidosis was made and the patient underwent surgery. Two years later, reoperation was required for hydatid cyst of the brain and cardiac cyst recurrence. There was no other organ involvement from the disease onset, which is rarely reported. Based on this case, we suggest that echocardiography be performed as a standard method in the diagnosis of anaphylactic reaction of obscure etiology in the areas endemic for hydatidosis, even in the absence of symptoms indicative of cardiac involvement. This especially applies to individuals with occupational or epidemiological exposure to the infection.
