To explore the MRI characteristics of the hepatic epithelioid hemangioendothelioma (HEHE) classification according to morphology and size. The clinical, pathological, and MRI imaging data of 40 cases with HEHE confirmed pathologically from December 2009 to September 2021 were retrospectively analyzed. A paired sample -test was used for comparison between the two groups.

A 58-year-old female was diagnosed with epithelioid hemangioendothelioma (EHE). The intrahepatic lesion exhibited a "Lollipop sign," associated with capsular retraction. On the PET/CT, there are multiple lesions in the lungs with variable high and low FDG uptake, and focal calcifications are present on CT.

Background: Hepatic epithelioid hemangioendothelioma (HEH) is extremely rare, and CT features have never been analyzed in a large group of patients.
Methods: A retrospective study was designed to review the contrast-enhanced CT images of HEH patients. Intrahepatic lesions were categorized into three types: nodular, locally coalescent (coalescent lesion contained in one segment) or diffusely coalescent (coalescent lesion occupied more than one segment).

Objective: To improve the current imaging understanding of MRI or CT for hepatic epithelioid haemangioendothelioma (HEHE) to aid in its successful preoperative diagnosis.
Methods: The imaging features of 15 patients (median age 38.6, range 20-71; 7 M/8 F) from eight institutions with pathologically confirmed HEHE were retrospectively analysed.

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare hepatic vascular tumor with a borderline biological behavior between hemangioma and hemangiosarcoma. It tends to be multiple or diffuse subcapsular lesions across the liver but has no characteristic clinical manifestations or imaging findings. On computed tomography and magnetic resonance imaging, these lesions usually have a hypodense appearance with heterogeneous enhancement and a "halo sign" or "lollipop sign" may be evident in some cases.
