24-year-old female with pain over the left sacroiliac joint. Evaluate for sacroiliitis. Note is made of mild increased signal abnormality along the inferior aspect of sacroiliac joints, left greater than right, which enhances on postcontrast sequences consistent with stated history of sacroiliitis which may be related to the patient's history of inflammatory bowel disease. There is also associated decreased signal abnormality about the sacroiliac joints which appears to correspond to sclerosis seen on recent CT examinations. The visualized musculature is normal in appearance. Multiple subcentimeter follicles are identified in the left and right adnexa. There is a 1.6 cm cystic lesion in the right adnexa which is likely physiologic in a patient of this age.
Findings consistent with bilateral sacroiliitis, left greater than right, which may be related to the patient's known history of inflammatory bowel disease.
