12 de ene. de 2024 · Solitary fibrous tumors are a rare neoplasm of mesenchymal origin that comprise less than 2% of all soft tissue tumors ranging from indolent tumors to more aggressive masses. They can be very large and can occur essentially anywhere, although some areas are more characteristic than others.
10 de jun. de 2021 · Abstract. Solitary fibrous tumor (SFT) is a rare mesenchymal, ubiquitous tumor, with an incidence of 1 new case/million people/year. In the 2020 WHO classification, risk stratification models were recommended as a better tool to determine prognosis in SFT, to the detriment of “typical” or “malignant” classic terms.
Abstract. BACKGROUND AND PURPOSE: Intracranial solitary fibrous tumors (ISFTs) are rare mesenchymal neoplasms originating in the meninges. The aim of this study was to describe the CT, MR imaging, and angiographic features of the solitary fibrous tumor and to identify imaging characteristics.
Solitary fibrous tumors (SFTs) are well defined hypervascular spindle cell neoplasms, occurring in a wide variety of locations. •. SFTs may be locally aggressive or may even metastasize. •. Benign and malignant SFTs may show uniform or heterogeneous contrast enhancement on CT and MRI. •.
