Fig. 3. Magnetic resonance imaging of brain and hip. (A) Horizontal view of the brain demonstrates multiple multilocular cystic bone lesions with internal hemorrhage and prominent wall enhancements involving the clivus, bifrontal skull base, bilateral sphenoid and left temporal bones (white arrows). (B) Coronal view of the hip with section at the femur head level revealed overall polyostotic bone tumors involving bilateral femurs as well as the ilium and sacrum (white arrows).
