Characteristic contrast‑enhanced ultrasound findings of hepatic epithelioid haemangioendothelioma: A case report and literature review

Abstract

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare liver tumor, which is usually diagnosed by pathological examination, since the diagnostic imaging criteria remain to be defined. However, contrast-enhanced ultrasound (CEUS) may reveal the characteristic features of HEHE to aid diagnosis. In the present study, two-dimensional ultrasound examination of a 38-year-old male patient showed a mass in the right liver. CEUS showed an S5 segment hypoechoic nodule, and imaging features resulted in the diagnosis of HEHE. Surgery was shown to be an appropriate and successful treatment for HEHE. In conclusion, CEUS may be valuable for the diagnosis of HEHE, thereby avoiding the serious consequences of misdiagnosis.
