中風合併色素絨毛結節性滑膜炎致患肢肩痛：病例報告

Abstract

Pigmented villonodular synovitis is an uncommon disorder characterized by synovial proliferation and hemosiderin deposition into the synovial lining of the affected joints, tendon sheaths and bursae. Its etiology is not fully known, however, inflammation, neoplasm and trauma have been postulated. It commonly affects the knee, hip, ankle and elbow joints, but rarely, the shoulder and its bursae. Shoulder pain is a common complication present in the stroke patients and its incidence varies from 5% to 84%. Shoulder subluxation, traction injury, contracture and reflex sympathetic dystrophy are the common causes of shoulder pain, whereas, pigmented villonodular synovitis is a very rare cause. The present report was to describe a case of stroke patient with shoulder pain caused by pigmented villonodular synovitis.A 72-year-old male patient was admitted due to left thalamic hemorrhage with right hemiplegia on January 3, 1994. Right shoulder pain associated with limited passive range of motion was noted during admission. Shoulder joint synovial fluid aspiration yielded a bloodtinged, brown fluid and the cytologic analysis revealed a low glucose content, low inflammatory cell count and a fair mucin clot. The magnetic resonance imaging showed localized hypertrophic synovium and hemosiderin deposit. Pathologic examination showed villous projection, hemosiderin deposit and prohferative synovial cells. Although uncommon, pigmented villonodular synovitis should be considered in the differential diagnosis of hemiplegic shoulder pain in the stroke patients.
