Abstract
Solitary fibrous tumors (SFTs) are a unique group of soft tissue tumors originating from fibroblastic or myofibroblastic tissue. SFTs rarely occur in the liver, with less than 30 cases reported in the literature. We report a case of SFT of the liver presenting unique imaging features on CT and MRI. A 52-year-old woman presented with an incidentally detected hepatic mass that showed homogeneous strong enhancement, starting from the arterial phase until the delayed phase images on CT. On the T2-weighted MR image, the mass was heterogeneously hyperintense with multifocal hypointense dots and bands within the mass. The mass was microscopically characterized by bland-looking, ovoid to spindle shaped cells with stromal and perivascular hyalinization. Immunohistochemical studies showed reactivity for CD34.
