RESUMO
Objective To explore the imaging differential diagnosis of vascular malformations and intermediary character hemangiomas.Methods The roentgenographic,CT and MRI findings of vascular malformations and intermediary character hemangiomas in 58 cases were analysed retrospectively.Results In 42 cases with vascular malformations,the lesions were irregular with definite margins,and 5 cases showed the bone compressed adjacent to the lesions.31 patients studied with MRI ,3 cases appeared as hyperintensity(equal to fat) and 28 cases appeared as mixed hyperintensity(higher than that of fat) on T2WI,20 cases showed circular markedly vessel-like hyperintensity on T2WI .In 16 cases with intermediary character hemangiomas,7 cases showed circular soft tissue masses,the masses were lobulated in 8 cases and "crab nail" in 1 case,5 cases showed edema of around the tumors and occupying effect on CT and MRI,3 cases showed bone corroded adjacent to the lesions,2 cases showed bony destruction.Of the 11 patients studied with MRI,the lesions showed hyperintensity on T2WI.Conclusion The imaging findings of vascular malformations and intermediary character hemangiomas are different.
