Abstract:
Objective To observe the clinical,CT and MRI manifestations of CIC-rear ranged sarcoma(CRS).Methods Eight patients with single CRS lesion ranged from 3.79 to 98.81 cm and the median of 21.37 cm were retrospectively enrolled,6 lesions located in deep soft tissue and 2 located in the femur.The clinical and imaging data were observed.Results All 8 CRS lesions presented as rapidly growing local masses,including 6 solid cystic soft tissue lesions and 2 non enlarged bone lesions with osteolytic bone destruction,which were all lobulated lesions with uneven equal-low density/slightly high T1 and slightly high T2 signals,with multiple focal map like necrosis.Diffusion weighted imaging showed lesions with limited diffusion and invasion of adjacent tissue,and"ice melting sign"was observed in 4 cases.After administration of contrast agents,the solid components of lesions enhanced unevenly and moderately or significantly and sustainedly,with slightly more pronounced enhancement at the edges,abundant blood vessels were visible inside and at the edges."Vascular floating sign"was noticed in 2 cases.Conclusion The clinical,CT and MRI manifestations of CRS had certain characteristics.
