Solitary Fibrous Tumor of the Liver: Magnetic Resonance Imaging Evaluation and Treatment With Transarterial Chemoembolization

Solitary fibrous tumor (SFT) is an uncommon neoplasm first described as a tumor of mesenchymal origin that rarely involves the liver. This report presents a rare case of unresectable SFT of the liver and documents the first use of transarterial chemoembolization in its treatment. Three sessions of chemoembolization were performed aiming to reduce the tumor size or at least stabilize it. Subsequent follow-up magnetic resonance imaging examinations were performed to assess imaging response to treatment. We recommend further studies to be done to assess both the use of transarterial chemoembolization in the treatment of unresectable SFT and the use of contrast-enhanced and diffusion-weighted magnetic resonance imaging for assessment of the tumor response to treatment.
