Imaging findings of primary malignant gastrointestinal stromal tumor of the liver

Jpn J Radiol. 2014 Jun;32(6):365-70. doi: 10.1007/s11604-014-0307-z. Epub 2014 Mar 29.

Abstract

A primary gastrointestinal stromal tumor (GIST) arising in the liver is extremely rare. In our case of GIST, CT and MRI showed a well-defined, weakly enhancing mass with a cystic component in the left lateral segment of the liver that showed homogeneous and avid (18)F-fluorodeoxyglucose ((18)F-FDG) accumulation on positron emission tomography/computed tomography (PET/CT). We herein present a rare case of primary malignant GIST of the liver presenting with peritoneal seeding on CT, gadoxetic acid-enhanced MRI and (18)F-FDG PET/CT.
