[Muscular hydatidosis. Apropos of 2 cases]

Muscular hydatid disease is uncommon. It usually consists in a primary single cyst which remains asymptomatic. Diagnosis is made upon pathological examination after a surgical procedure carried out to establish the cause of a swelling. Indeed, in most cases serology is not helpful and, moreover, it rapidly becomes negative after surgery. We report two cases and discuss the features of this condition.
