Abstract:
Purpose To analyze and compare the imaging characteristics of contrastenhanced ultrasound (CEUS) and dynamic contrast-enhanced CT for hepatic epithelioid hemangioendothelioma (HEHE) diagnosis.Materials and Methods The imaging characteristics of CEUS and dynamic contrast-enhanced CT performed on 16 patients with pathological-confirmed HEHE were retrospectively analyzed.Dynamic contrast-enhanced CT was performed on 5 patients,real-time CEUS was performed on 8 patients,and both examinations were performed on 3 patients.Results On CEUS,14 lesions were selected from 11 HEHE cases.In the case of enhancement mode,5 lesions displayed ringenhancement,and 9 lesions displayed global enhancement;in the case of arterial phase,11 lesions were synchronously enhanced,and 3 lesions were rapidly enhanced compared with liver parenchyma;in the case of peak time,hyper-enhancement,iso-enhancement and hypo-enhancement were observed in 2 lesions,9 lesions and 3 lesions,respectively;all 14 lesions manifested hypoechoic mass in portal phase and delayed phase.On dynamic contrast-enhanced CT,29 lesions were found in 8 HEHE cases.In the case of arterial phase,9 lesions (31.0％) showed slight inhomogeneous enhancement,4 lesions (13.8％) showed no obvious enhancement and 16 (55.2％) lesions showed slight edge enhancement;all 29 lesions presented continuous hypo-enhancement in delayed phase.Conclusion Both CEUS and dynamic contrast-enhanced CT have respective characteristic manifestations,and are of high value for the diagnosis of HEHE.
