Abstract
BackgroundMusculoskeletal hydatid cysts are rare, but being locally invasive, can potentially cause significant deformity or pathological fracture.Case presentationA 39 y.o. male presented to our orthopaedic outpatient clinic complaining of severe right hip pain, and inability to ambulate. Symptoms were not preceded by trauma. Subsequent imaging confirmed a large, 17 × 3 × 5 cm echinococcus cyst in the vastus lateralis, causing erosion of the proximal metaphysis of the femur. As a consequence the patient suffered a non-traumatic pathological intertrochanteric femur fracture. The patient was treated with an en-bloc excision of the lesion - the affected soft tissue envelope containing the large cyst - and as a second surgical step a cemented total hip replacement (THR) was implanted under the same anaesthetic.The manuscript reviews the literature regarding musculoskeletal hydatid disease.

Among Echinococcus species, E. granulosus and E. multilocularis are commonly reported to be responsible for human hydatidosis
In this paper we report a rare case of a hydatid cyst located in the soft tissues of the right thigh and involving the proximal femur
