Discussion: The iliopsoas bursa is the largest bursa in the body. It is located anterior to the hip joint next to the femoral neurovascular bundle and iliopsoas muscle. The bursa communicates with the hip joint in 15% of individuals. Normally, the bursa is not visualized on imaging. However, the bursa can become distended and cause pain in patients with infection, rheumatoid arthritis, or osteoarthritis. In such cases, CT will demonstrate a fluid collection in the characteristic location. On MRI, iliopsoas bursitis will appear as high signal intensity on T2-weighted sequences and low intensity on T1-weighted sequences. With contrast, the bursal sac enhances, but the contents, do not.
