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

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).

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

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).
