Abstract

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.

염증성 근섬유모세포종(inflammatory myofibroblastic tumor)은 드문 종양으로, 조직학적으로 근섬유모세포성 방추세포의 증식과 다양한 염증 세포들의 침윤을 특징으로 한다. 이 종양은 전신의 모든 해부학적 위치에서 생길 수 있으나 주로 폐, 장간막, 대망에서 생긴다고 보고되어 있으며, 대부분의 경우 어린이 또는 젊은 성인에서 발생한다. 췌장에서 발생하는 경우는 매우 드물며, 악성 종양을 포함한 다른 종양과 구별하기 어렵기 때문에 정확한 영상의학적 진단이 어려운 경우가 흔하다. 이에 저자는 중년 여성의 췌장 두부에서 발생한 염증성 근섬유모세포종의 사례를 초음파, 컴퓨터단층촬영, 자기공명영상 소견들과 함께 제시하고 문헌을 검토하고자 한다.
