Eggs arepassed in feces and eaten by intermediate hosts and larvae encyst in the liver, lungs and other organs. Primarymuscular hydatidosis without involving the thoracic or abdominal organs is extremely rare. A case ofintramuscular gluteal hydatid cyst is being reported with the intent of highlighting this atypical localization ofthe disease. Since the soft tissue tumors may be confused with hydatid cysts, preoperative evaluation ofthese patients is critical for proper handling during surgery to avoid life-threatening complications.
