Inflammatory myofibroblastic tumors are rare, especially in the pancreas. It is sometimes difficult to obtain a definitive diagnosis with radiological imaging and there is not yet consensus about treatment. We report a case of a 56-year-old man with recurrent abdominal pain particularly in the right upper quadrant without other symptoms. The imaging results showed a pancreatic hypovascularized mass with stenosis of the main pancreatic duct and the common bile duct without metastasis. The FDG PET scanner showed two hypermetabolic foci in the head of the pancreas. The biopsies of the mass were not diagnostic. The therapy adopted was Whipple's pancreaticoduodenectomy with a histological diagnosis of the inflammatory myofibroblastic tumor.
炎性肌纤维母细胞瘤较为罕见，尤其是发生在胰腺时。有时通过放射影像学检查很难做出明确诊断，而且在治疗方面尚未达成共识。我们报告一例56岁男性病例，该患者反复出现腹痛，尤其是右上腹疼痛，无其他症状。影像学检查结果显示胰腺有一个血供减少的肿块，主胰管和胆总管狭窄，无转移。FDG PET扫描仪显示胰腺头部有两个高代谢灶。肿块活检未能明确诊断。所采用的治疗方法是惠普尔胰十二指肠切除术，术后组织学诊断为炎性肌纤维母细胞瘤。
