Abstract:
Objective To analyze the imaging appearances of solitary fibrous tumors (SFT) of the lower limb.Methods The imaging manifestations of SFT of the lower limb proved with pathology in 2 patients were reported and the relevant literatures were reviewed.All patients underwent MR examination,and 1 received skeletal radiography.Results Both tumors were mainly located within the biceps muscle of thigh.MR demonstrated that the tumor appeared as a solitary round or oval well circumscribed mass,with inhomogeneous low to intermediate intensity signal on T1WI and heterogeneous low to high intensity signal on T2WI.Inhomogeneous enhancement was demonstrated on T1WI.Marked enhancement of solid components in the tumor was identified.No bone destruction was found on plain film.Conclusion There are some characteristics on the imaging of SFT of the lower extremity.MRI is the optimal imaging method for the diagnosis of this disease.
