Hydatid cyst disease is a parasitic infection caused by Echinococcus granulosus. Hydatid cyst disease is endemic in our country. This disease is most commonly detected in the liver and lung. Primary soft tissue involvement is very rare, causing a diagnostic challenge. Turkey is an endemic area for hydatid cyst disease and we should bear this disease in mind as a differential diagnosis in all cystic lesions. In this study, we mentioned a hydatid cyst case in gluteus maximus muscle without any primary lesion.
