Abstract:
Objective To observe imaging manifestations of infantile fibrosarcoma (IFS).Methods Imaging features of histopathologically proved IFS in 7 patients were retrospectively analyzed.The location,margin,morphous,size,echoic/ density/signal intensity,metastasis,invasion and vascularity of tumors were observed.Results The tumors located in extremities (n =5),trunk (n =1) or abdomen (n =1),respectively.Ultrasound showed irregular morphology,heterogeneous hyper-echoic areas with circumscribed margin in all 7 patients.The lesions in 5 cases were iso-hyperechoic,2 were iso-hypoechoic.Anechoic areas and abundant tumor blood flow signals were demonstrated.CT (n=5) showed heterogeneous soft-tissue masses with heterogeneous enhancement.No calcification,bone erosion nor distant metastasis was found with CT.The lesions usually showed inhomogeneous signal intensity on T1WI or T2WI,with heterogeneous enhancement after contrast administration.Conclusion Imaging examination can clear show the morphous,size,internal architecture and vascularity of tumors as well as relationship with surrounding tissues of IFS.
