case_images: Standard radiographs and CT scan of the pelvis were normal (Figure 1).

case_images: T2 sequence of the acetabular roof, without bone destruction or invasion of the hip joint (Figure 2). This abnormal signal can not be associated with a particular pathology. The bone scintigraphy shows increased uptake at the right acetabulum (Figure 3).

case_images: 3 months after first MRI, reduction of oedema in the roof of the acetabulum without bone lesion

case_images: After this period, the pain decreased remarkably and MRI showed a diminution of oedema in the roof of acetabulum (Figure 4).
case_images: 6 months after first MRI: complete regression of the oedema and the high signal on T2

case_images: MRI showed a complete regression of the oedema and the signal of the acetabulum was normal corresponding to the healing stage of the stress fracture (Figure 5).
