[Intramuscular hydatid cyst: a case report].

The muscular localization of the hydatid cyst is uncommon (0.5 to 5.4%) and it is usually secondary to hepatic or pulmonary disease. A case of gluteus intramuscular hydatid cyst is reported, calling attention to this atypical localization of the disease, which should be taken into account in the practice of surgery. The absence of residual cysts in the most common sites confers a higher interest to the case reported in this work.
