Aggressive lytic lesion of lesser trochanter proximal femur in an eighteen year old male - A case report

Aneurysmal bone cyst (ABC) is an osteolytic benign tumour, which is usually situated in the metaphysis of long bones and mostly encountered in patients younger than 20 years old. Common treatment modalities include arterial embolization, curettage, intralesional injections and en-bloc resection with instrumentation. We present a case of an eighteen-year old male with an ABC involving lesser trochanter of left femur with impending pathological proximal femur fracture. We discuss treatment modalities and clinical outcome in our case. Keywords: Aneurysmal bone cyst, Expansile lytic cyst, Lesser trochanter tumour, Proximal femur.
