Iliopsoas bursitis: clinical features, radiographic findings, and disease associations.

Inflammation of the iliopsoas bursa is a common manifestation of a wide array of inflammatory, degenerative, and traumatic musculoskeletal conditions. The clinical presentation of iliopsoas bursitis is variable, and includes pain, mass lesion, or compression syndromes of the inguinal compartment. Affected individuals frequently have underlying synovitis of the hip or a history of occupational or recreational injury. Early and accurate diagnosis is facilitated by appropriate radiographic studies.
