Osteitis condensans ilii (OCI) is a benign joint condition, which is most often seen in young multiparous women. It is essentially diagnosed by radiological findings which reveal a bilateral and symmetrical sclerosis of iliac sides of sacroiliac joints or narrowing. A 30-year-old woman presented with a ten-year history of low back pain and buttock pain. She was a nulliparous woman and had no history of pregnancy. Her low back pain was mild and developed intermittently. Physical examinations and laboratory studies were unremarkable. Plain X-ray showed bilateral sclerosis of the iliac bones adjacent sacroiliac joints. Computed tomography confirmed the sclerotic changes in both iliac bones without a bony change in sacrum. There is no joint space narrowing or bony erosion in the sacroiliac joints. On the basis of the imaging studies, she was diagnosed as OCI and treated symptomatically with non-steroidal anti- inflammatory drugs. After the symptomatic treatment, her symptom was improved.
