A 23-year-old patient with a history of hemoglobinopathy (B-thallasaemia) and osteonecrosis of the left hip, which was treated with porous tantalium rod implantation. The patient presented at the follow up examination with multiple painful sites in the pelvis. Plain AP x-ray of the pelvis was negative (a). The coronal fat suppressed T2-w TSE images (b-d) depicted multiple bone infarcts bilaterally at the ischiac bones, acetabuli and proximal femoral diaphyses.
