A case of femoral nerve palsy caused by iliopectineal bursitis associated with rheumatoid arthritis

We report the case of a 46-year-old woman with rheumatoid arthritis who developed femoral nerve palsy caused by an enlarged iliopectineal bursa. Surgical excision revealed that the iliopectineal bursa was connected with the hip joint. The patient showed good recovery from the femoral nerve palsy after surgery. It was considered that iliopectineal bursitis had developed following the synovial inflammation of the hip joint.
