Case Discussion
Femoral neck fractures that are invisible on plain radiographs and CT are called "occult" and should be suspected in elderly osteoporotic patients who present with hip pain and refuse to bear weight after a fall. In these cases, a diagnosis of femoral neck fracture can only be made with MRI.
