Reason: possible insufficiency fractures vs mets in pelvis History: possible insufficiency fractures vs mets in pelvis There is linear decreased signal abnormality traversing the right ilium adjacent to the right sacroiliac joint with associated increased signal abnormality on fluid sensitive sequences indicating a insufficiency fracture. There is enhancement about the right ilium insufficiency fracture as well on postcontrast sequences. There is also linear decreased signal abnormality within the right sacral wing with associated increased signal abnormality on fluid sensitive sequences also likely reflecting an insufficiency fracture. Additionally, there is enhancing signal abnormality within the left ilium which is associated with increased bone marrow signal abnormality on fluid sensitive sequences as well as peripheral enhancement on postcontrast sequences and soft tissue extension corresponding to the findings on recent CT examination. The imaged musculature of the pelvis are otherwise unremarkable. Note is made of foci of metallic susceptibility artifact along the midline of the lower abdomen and pelvis presumably reflecting postsurgical changes.
1. Enhancing lesion in the left ilium with associated soft tissue extension suspicious for osseous metastatic disease. 2. Multiple insufficiency fractures as described above.
