多房性腸恥滑液包炎を伴った急速破壊型股関節症の1例

Rapidly Destructive Hip Disease with Multilocular Iliopectineal Bursitis. Case Report

　急速破壊型股関節症に伴った，囊胞壁に石灰化を認める多房性の腸恥滑液包炎と思われる稀な症例を経験したので報告する．症例は59歳の女性である．関節リウマチが基礎疾患として存在した．左股関節痛が出現し8カ月で左大腿骨頭の破壊を認め，急速破壊型股関節症と思われた．MRIで左股関節と連続し左腸骨内板に接する大きな多房性囊胞性病変(腸恥滑液包炎)を，CTでは囊包壁に石灰化を認めた．多房性囊胞性病変は処置せず左急速破壊型股関節症に対しセメント人工股関節置換術を施行した．人工股関節置換術後3年のCTでは多房性囊胞性病変の消失を確認した．

　We report a rare case of rapid destructive coxarthrosis of the left hip joint accompanied by multilocular calcified iliopectineal bursitis.　A 59-year-old woman was found to have destruction of the left hip joint 8 months after she began to experience left hip pain.　The postoperative diagnosis was rheumatoid arthritis.　MRI demonstrated extensive multilocular iliopectineal bursitis in the left hip, and CT showed calcification of the wall of the bursa.　Left total hip arthroplasty was performed without treating the bursitis.　CT 3 years later demonstrated that the iliopectineal bursitis had resolved.
