A Case Report of a Hydatid Cyst on the Right Thigh in a 9-Year-Old Girl: A Difficult Diagnosis

Background: Hydatid disease is a parasitic infection that occurs primarily in Mediterranean countries. Skeletal and muscular involvement is a rare feature of hydatid disease, making the diagnosis of this condition difficult, especially in children.

Conclusion: It is important to pay attention to the rare localization of hydatid cysts in endemic areas, particularly in children.
