Solitary fibrous tumor in the abdomen and pelvis: A case series with radiological findings and treatment recommendations.

This study presents the radiological findings of seven cases of solitary fibrous tumor (SFT) in the abdomen and pelvis. A retrospective search of the pathology database at our institution was performed to identify cases of SFT in the abdomen and pelvis. After identifying seven cases, cross-sectional imaging was reviewed and characterized. We conclude that SFTs in the abdomen and pelvis should be considered with well-defined, circular, hypervascular masses. Pelvic SFTs should be considered with homogenous, avidly enhancing masses. Embolization of feeding arteries can allow safe surgical resection or biopsy, but embolization appears to not offer a definitive therapy.
