Acute hip pain: mimics of a femoral neck fracture.

Acute hip pain is a common presenting complaint among patients attending Emergency Departments particularly following a traumatic event. A proximal femoral fracture is the main consideration, which requires urgent confirmation and treatment; however, there are a number of conditions, which could mimic neck of femur fracture and the causes may not be directly related to the hip, so systematic and careful observation of pelvic MRI could shed light on the true culprit of acute hip pain.
