A well defined, expansile, heterogeneous signal intensity lesion is noted involving the right iliac blade, pubic rami (both inferior and superior ramus of pubic bone), ischium, reaching up to the articular surface of the acetabulum and involving the head of the femur with adjacent soft tissue component. This lesion appears iso-intense on TIWI and predominantly hyperintense on T2WI and STIR. On postcontrast study, it shows heterogeneous enhancement.
