[Histopathological and imaging features for soft tissue liposarcoma of extremities].
OBJECTIVE
To analyze the histopathological and imaging features for soft tissue liposarcoma of extremities and to provide guide for clinical diagnosis.


METHODS
Nine patients with soft tissue liposarcoma of extremities received treatment in Qinghai University Affiliated Hospital from October 2012 to October 2014. The imaging features of CT and MRI as well as the histopathological features were retrospectively analyzed. The pattern, size and border of tumor were observed, and the correlation between the pathological features and the imaging features was analyzed.


RESULTS
Lower limb lesion was found in 8 patients, including the left lower leg, left and right thigh, respectively. One patient had right upper arm lesion, 1 case had bleeding, and 1 case displayed with calcification and liquefaction performance. The CT examination showed low density shadow and linear separated shadow. The ultrasound examination displayed different intensity fat-like echo. There was short signal intensity on T1 weighted imaging and long signal intensity on T2 weighted imaging in MRI.


CONCLUSIONS
MRI and other imaging examinations show good performance in detecting the features of soft tissue liposarcoma of extremities, which possess diagnostic value.
