Abstract

Leiomyoma is a common benign tumor from smooth muscle cells, mostly in the uterus. Peritoneal leiomyomas (PLs) are extremely rare and mostly reported as disseminated peritoneal leiomyomatosis. However, to the best of out knowledge, radiologic findings of isolated PL are not reported in English literature. Herein, we introduce the radiologic findings of PL mimicking hepatic mass in a 34-year-old female. CT showed a mass with curvilinear heterogeneous enhancement at the liver's peripheral area. On MRI, the mass showed gradual and heterogeneous enhancement on gadoxetic acid-enhanced MRI and diffusion restriction. The radiologic diagnosis was a benign hepatic tumor, such as degenerated hemangioma, adenoma, and inflammatory myofibroblastic tumor; however, the mass was diagnosed as PL pathologically.

평활근종은 평활근세포에서 발생할 수 있는 흔한 양성종양으로, 주로 자궁에서 발생한다. 복막평활근종은 매우 드물며 대부분 복막성 평활근증으로 보고되었다. 저자들이 아는한 단일 복막평활근종의 영상의학적 소견은 영문으로 아직까지 보고된 바가 없다. 전산화단층촬영에서 비균질한 조영증강, 자기공명영상에서 점진적 조영증강 및 확산제한을 보여 영상의학적으로 간의 변성된 혈관종, 간선종, 혹은 염증성 근섬유아세포종 등을 감별하였으나 수술 후 병리학적으로 복막평활근종으로 진단된 34세 여성의 증례 및 영상의학적 소견을 보고하고자 한다.
