Pain. Left ilium lesion. There is a mixed sclerotic/lucent lesion within the left ilium adjacent to the sacroiliac joint corresponding to that seen on prior CT and MRI studies measuring approximately 5 cm in maximum dimension. Based on the previous studies I suspect that this represents an intraosseous lipoma which would showed fat signal intensity, suggestive of a suspect this represent an intraosseous lipoma at or potentially a intraosseous "hemangioma". Surgical clips are noted within the pelvis on the left.
Mixed lucent/sclerotic lesion in the left ilium containing fatty components on prior imaging studies. This may represent an intraosseous lipoma or perhaps a intraosseous "hemangioma".
