Abstract:
OBJECTIVETo investigate the imaging characteristics of abdominal solitary fibrous tumor (SFT) with its pathological features.
METHODSSix cases of abdominal solitary fibrous tumors were studied using X-ray, CT, MRI examination as well as histopathological and immunohistochemical techniques.
RESULTContrast enhanced CT showed early intense enhancement as a result of the rich vascularization. On MRI the parenchyma of the tumors showed hypointensity on T1WI, T2WI and some tumors might manifest areas of hyperintensity on T2WI due to myxoid degeneration or hemorrhage. Microscopically, SFT was composed of spindle cells with various patterns and these spindle cells were CD34 positive on immunohistochemistry.
CONCLUSIONSFT is a soft tissue tumor originating from mesenchyma. Abdominal SFT shows variable appearance and enhancement pattern on CT and MRI according to tumor cells distribution and myxoid degeneration or hemorrhage within the tumor pathologically.
