Inflammatory myofibroblastic tumors (IMTs) are rare. They are characterized by myofibroblastic spindle cell proliferation with a varying degree of inflammatory cell infiltration. IMT can occur in any anatomic location but has been reported in the lung, mesentery, and omentum, mainly in children or young adults. It rarely occurs in the pancreas and is often difficult to distinguish from other tumors, including some malignant ones. Therefore, it can be challenging to make a radiological diagnosis of IMT. Here, we present a case of IMT that occurred in the pancreas head of a middle-aged female. The patient's ultrasonography, computed tomography, and magnetic resonance imaging findings are presented along with a review of the literature.
炎性肌纤维母细胞瘤（IMTs）较为罕见。它们的特征是肌纤维母细胞梭形细胞增殖，并伴有不同程度的炎性细胞浸润。IMT可发生于任何解剖部位，但已报道多见于肺、肠系膜和网膜，主要发生于儿童或年轻人。它很少发生于胰腺，且常常难以与其他肿瘤（包括一些恶性肿瘤）相鉴别。因此，对IMT进行影像学诊断可能具有挑战性。在此，我们报告一例发生于中年女性胰头的IMT病例。展示了该患者的超声、计算机断层扫描和磁共振成像结果，并对相关文献进行了综述。
