Abstract: Aneurysmal bone cysts are enigmatic, locally destructive blood filled lesions of bone with unknown cause & unusual presentations. We report a case of an 8-year old male child who presented to us with a pathological fracture of right hip after a trivial fall. It was an aggressive aneurysmal bone cyst of the proximal femur complicated by a subtrochantric fracture. Treatment was done successfully with an intralesional curettage and implantation of a frozen cancellous cadaveric allograft of femoral head followed by internal fixation of the pathological fracture with plate and screw.
