CT in diagnosis of infantile hepatic hemangioendothelioma / 中国医学影像技术

ABSTRACT

Objective To explore the CT features of infantile hepatic hemangioendothelioma (IHH).Methods CT imaging features of 16 IHH patients confirmed by surgical pathology and clinical diagnosis were retrospectively reviewed.Results Of 16 patients,there were single lesion in 10 cases and multiple lesions in 6 cases.All the lesions were rich in blood supply,and the arterial phase showed obviously rings enhanced.Some linear enhancement towards to the center below the annular enhancement of solitary lesions were found.There were patchy enhancement in annular enhancement center area,and the area of enhancement obvious increasing in venous phase and delayed phase in 4 cases with multiple lesions,enhancement mode was similar to single lesion in 1 case with multiple lesions.The lesions of IHH Ⅱ were small and multiple,and showed intermittent line shaped edge enhancement;some lesions below the linear enhancement showed small nodular enhancement and the area of nodular enhancement enlarged in venous phase,the range of linear enhancement was not obvious.Conclusion CT manifestations of IHH have some characteristics,and the enhancement of CT is more important in the diagnosis of this disease.
