CT and MRI features of hepatic epithelioid haemangioendothelioma: a multi-institutional retrospective analysis of 15 cases and a literature review

Abstract

Key points “Target signs” and “lollipop signs” should be recognised in imaging evaluation, raising the possibility of HEHE in the differential diagnosis. Abnormal blood vessels in tumours may have implications for imaging diagnosis. When HEHE is suspected, radiologists should be aware of tumour thrombi in the vena cava. HEHEs always present with a peripheral enhancement of various shapes with centripetal progressive filling.
