Abstract

初診時の身体所見上凍結肩と診断したが，その後に撮像したMRIにて腱板筋筋腹の信号変化を認めた症例を経験した．MRIにて腱板筋付着部・筋腹がT2強調像・STIR像共に高信号を呈した6肩である．初診時1例は疼痛強く自動運動困難で，他の5例の可動域平均は屈曲50° ，外旋8° ，内旋は第5腰椎レベルであった．それぞれバセドウ病，骨髄異形成症候群にて同種臍帯血移植後，腎機能低下あり尿中BJP陽性，RAとシェーグレン症候群合併，胃癌術後化学療法中，腎癌術後再発にて化学療法中であった．これらの症例は関節内ステロイド注射などの治療が奏功せず，原病の病勢に症状が関連し，原病の治療が重要であると考えられた．
