抄録

症例は78歳男性.他院で胆石症に対して腹腔鏡下胆嚢摘出術を施行された.術前のMRIで偶然,膵体部に18mmの腫瘤を認めた.膵体部腫瘤の精査,加療目的に入院となった.造影CTでは周囲より緩徐に造影される22mmの腫瘤として描出され,超音波内視鏡では不整形で内部に不均一な高エコー領域を伴う腫瘤として描出された.PET検査で集積を認めないものの膵癌が否定できず,膵体尾部切除を施行した.病理診断にて黄色肉芽腫性炎症性腫瘤と診断された.膵の黄色肉芽腫性腫瘤は非常に稀であり,文献的考察を加えて報告する.<br>

A 78-year-old man had undergone laparoscopic cholecystectomy for cholecystolithiasis at another hospital. Preoperative magnetic resonance imaging incidentally revealed an 18mm mass lesion in the pancreatic body. After the operation, he was referred to our hospital for further examination and treatment of the pancreatic mass. On admission, he was afebrile and asymptomatic. Contrast-enhanced computed tomography showed a 22mm mass lesion in the pancreatic body which was mildly enhanced. Positron emission tomography-computed tomography scan showed no fluorodeoxyglucose uptake in the mass. Endoscopic ultrasonography showed a hypoechoic irregular mass. On the basis of the findings from the imaging series, he was likely to have a solid pancreatic neoplasm, therefore surgery was performed. Histological examination revealed fat necrosis with xanthogranulomatous inflammatory (XGI) change. XGI of the pancreas is an extremely rare condition. Herein, we report a case of XGI of the pancreas mimicking a pancreatic neoplasm.<br>
