ABSTRACT
Objective To investigate the imaging findings of CT and MRI in patients with abdominal and pelvic solitary fibrous tumor and its pathological features.Methods 30 patients with abdominal and pelvic solitary fibrous tumor were chosen.Patients with CT and MRI,and pathologic features control study were analyzed.Results In 30 patients,mesenchymal tumors,malignant fibrous histiocytoma and ovarian fibroma patients were 12 cases,12 cases, 6 cases.CT showed that mass state clearly,smooth contours,the substance of the composition of two different densi-ties,increase significantly enhanced scan,saw a number of tumor blood vessels within the shadow arterial aneurysm. MRI showed that internal tumors were low signal stripes appear.Tumor necrosis internal punctate liquefaction zone, after enhanced scan,the patient did not appear to strengthen.6 patients had resection specimens.4 cases had a more complete capsule,two cases with incomplete capsule.Conclusion SFF has certain characteristics in CT and MRI imaging screening,combined with its pathological features analysis will help improve the diagnosis.
