Abstract

An inflammatory myofibroblastic tumor (IMT) is a rare disease and can occur in nearly every site of the body. The usual intrathoracic sites where an IMT has been recorded are the lung and bronchus. An IMT originating from the mediastinum has been rarely reported. A patient with a posterior mediastinal mass that was noticed incidentally on a chest X ray underwent mass extirpation. The pathologic diagnosis was an inflammatory myofibroblastic tumor. The tumor was positive for tuberculosis as determined by PCR. Tuberculosis can be thought to be the causative factor of the IMT in this case.

염증성 근섬유모세포종은 드문 질환이며 인체의 거의 모든 위치에서 발생할 수 있다. 흉부영역에서 염증성 근섬유모세포종이 주로 발생하는 위치는 폐와 기관지이다. 종격동에서 발생한 염증성 근섬유모세포종은 보고된 경우가 드물다. 흉부 방사선 촬영에서 우연히 발견된 후종격동 종괴를 가진 환자에서 종괴적출술을 시행하였다. 조직검사결과 염증성 근섬유모세포종으로 진단되었고, 결핵 PCR 양성을 보였다. 본 증례에서 결핵이 염증성 근섬유모세포종의 유발인자로 고려될 수 있었다.
