Pelvic radiograph in a patient with osteopetrosis type II

Anteroposterior pelvis views of a patient with autosomal dominant osteopetrosis type II. Note the concentric rims around the iliac wing secondary to areas of increased bone density often known as bone-in-bone image. There is increased bone density inside the lumbar vertebral bodies. The proximal femurs showed a generalized increase in bone density and decrease of intramedullary spaces.
