 note = {今回われわれは,悪性腫瘍術後で転移性肝腫瘍が疑われたが,経皮的針肝生検により肝炎症性偽腫瘍と診断し得た症例を経験した.症例は67歳の男性.十二指腸乳頭部癌に対する膵頭十二指腸切除術の既往がある.糖尿病のために当院の内科に入院し,腹部超音波検査で肝腫瘍が指摘された.発熱はないが,炎症所見と胆道系酵素の上昇を認めた.腫瘍マーカーは正常値であった.種々の画像検査で転移性肝腫瘍が疑われたが確定診断は得られなかった.そこで経皮的針肝生検を行い,組織学的に炎症性肉芽組織と判断され,肝炎症性偽腫瘍と診断した.肝炎症性偽腫瘍は炎症性細胞の浸潤と線雄性組織の増生による腫瘤が肝に形成される疾患である.その発生要因は不明であるが感染が有力視され,慢性肝膿瘍と同一疾患と考えられている.自験例は,組織学的所見より膵頭十二指腸切除術後の晩期合併症としての胆管炎から肝膿瘍が形成され,それが瘢痕化したものと推察した., The patient was a 67 year-old man who had undergone pancreaticoduodenectomy for duodenal papillary cancer. He was admitted to the Department of Medicine for the treatment of diabetes mellitus and a liver tumor was found by abdominal ultrasonography. Although the patient did not have fever, elevated inflammatory markers and biliary enzymes were observed, while tumor markers were normal. Various imaging studies suggested a metastatic liver tumor, but a definitive diagnosis was not possible. Therefore, percutaneous needle liver biopsywas performed and a diagnosis of inflammatory pseudotumor of the liver was made. Inflammatory pseudotumorof the liver is a hepatic mass formed by the infiltration of inflammatory cells and the proliferation of fibrous tissue. From the histological findings, this patient was concluded to have a resolving liver abscess that had formed due to cholangitis as a late complication of pancreaticoduodenectomy.},
