Female 18 years old with right hip pain. Evaluate for active sacroiliitis. The sacroiliac joints are normal in appearance. There is no ankylosis and no erosions are seen. Bone marrow signal intensity is within normal limits and there is no enhancement on postcontrast images. A small, approximately 8 mm, T2 hyperintense lesion is partially visualized in the right ilium. This may represent a small cyst or possibly an enchondroma and is likely of no clinical significance.A cystic left adnexal lesion measures up to 5.6 x 4.4 cm but is not fully visualized and therefore incompletely characterized.
