title: Iliopsoas bursa of the rheumatoid hip joint. A case report and review of the literature.
abstract: Presented is the case of a 63-year-old woman, with a 30-year history of rheumatoid arthritis, whose hip was completely destroyed and accompanied with enlargement of the iliopsoas bursa. Preoperative diagnosis was confirmed by computed tomography, magnetic resonance (MR) imaging and arthrography. She was treated by resection of the iliopsoas bursa and total prosthetic replacement of the hip joint. The pathogenesis is uncertain. In the literature, enlargement of the iliopsoas bursa with rheumatoid arthritis, osteoarthritis, pigmented villonodular synovitis, and synovial chondromatosis had been reported. Nevertheless, a correct preoperative diagnosis of the enlargement of the iliopsoas bursa is very difficult. MR imaging with enhanced Gadolinium-DTPA (Gd-DTPA) is proposed as the most useful examination for preoperative diagnosis.
