A case of surgical approach to the mesenteric panniculitis

症例は50代男性.左下腹部の腫瘤を主訴に受診となり,腹部エコー,腹部CT,下部消化管内視鏡,注腸検査等で腸間膜脂肪織炎が疑われた.抗生剤の投与を行い約1ヵ月間経過観察としたが,体調不良の訴えが継続し,体重減少も著明で悪性疾患の可能性も否定できないため開腹手術が施行された.病理組織学的にS状結腸漿膜下組織に炎症細胞浸潤,線維芽細胞及び膠原線維の増生,漿膜に線維素が析出しており,腸間膜脂肪織炎の線維化の段階と考えられた.腸間膜脂肪織炎は稀な疾患であり,今回画像診断を中心に文献的考察を加えて報告する.

A 53-year-old man visited our hospital with the chief complaint of a mass in the left lowerquadrant. Mesenteric panniculitis was suspected after abdominal echography, abdominal computed tomography, colonoscopy, and barium enema. He received an antibiotic and was under observation for about a month because he complained of physical deconditioning continually and showed remarkable weight loss, which might be associated with a malignant disease. Laparotomy was performed, and histopathological analysis showed inflammatory cell infiltration, fibroblast and collagen fiber proliferations deposited at the sigmoid colon subserosa, and fibrin deposited at the serosa
