Sacral lesion There is a 2 cm focus of low signal intensity (signal void) on all sequences within the left sacral wing. This focus does not demonstrate enhancement and is representative of a benign bone island. There is no abnormal enhancement elsewhere in the pelvis.The hips appear normal for age. There is mild peritrochanteric edema bilaterally which is not necessarily of any clinical significance. There is mild osteoarthritis of the sacroiliac joints and minimal degenerative disc disease of the lower lumbar spine. The remaining visualized soft tissues are unremarkable.
