Sudden death caused by hydatid embolism.

An 18-year-old man died on the spot during a foot race. Previously, he had been in a healthy condition. Since the cause of his sudden death was unknown, a forensic autopsy was carried out. The autopsy revealed hydatid cysts in the right ventricle of the heart some of which had embolized the pulmonary arteries. In case of sudden death in endemic areas the possibility of a hydatid disease should be taken into consideration.
