case_images: (A) MR study of the pelvis which demonstrates a right femoral neck stress fracture on the compression side type that involves >50% of the cortical bone. (B) Radiograph of the right hip demonstrating postoperative changes status-post closed reduction percutaneous pinning of the femoral neck using three cannulated screws. (C) MR study of the left hip which demonstrates a left femoral neck stress fracture on the tension side that is unicortical. (D) Radiograph of the left hip demonstrating postoperative changes status-post closed reduction percutaneous pinning of the femoral neck using three cannulated screws.

case_images: MRI of the lower right extremity demonstrated high signal intensity edema in the bone marrow at the inferior medial aspect of the right femoral neck; findings that are consistent with a compression stress reaction (Fig. 1). MRI of the lower left extremity demonstrated high signal intensity edema in the bone marrow at the superior-lateral aspect of the left femoral neck (Fig. 1).
