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.

Figure

  • Fig. 1 A 52-year-old woman with a solitary fibrous tumor of the liver, presenting with an incidentally detected hepatic mass. A. Axial ultrasonogram shows a relatively homogeneous hypoechoic mass (arrow) in the left lateral segment of the liver. B. The unenhanced axial CT image shows a well-defined low attenuated mass (arrow) in the left hepatic lobe. The mass is vividly enhanced on the portal venous phase CT image and persistently enhanced on the delayed phase CT image. C. Fat-saturated T2-weighted magnetic resonance image depicts a heterogeneous hyperintense mass and multifocal hypointense dots and bands within the mass. D. On gadoxetic acid-enhanced MRI, the mass appears homogeneously hyperintense and hypointense on the arterial and hepatobiliary phases, respectively. E. The gross surgical specimen appears as a well-defined exophytic mass with a whitish cut surface. F. Photomicrograph shows bland-looking, ovoid to spindle shaped cells with stromal and perivascular hyalinization (hematoxylin-eosin staining, × 100). On immunohistochemical staining, the tumor cells show reactivity for CD34 (× 200).
