Quantitative assessment of multi-phase contrast-enhanced CT features in hepatic epithelioid hemangioendothelioma.

ABSTRACT:

Background

Hepatic epithelioid hemangioendothelioma (HEH) is a rare vascular malignancy with imaging features often overlapping with hepatic metastatic tumors (HMTs), leading to frequent misdiagnosis. Current diagnostic reliance on qualitative imaging signs lacks specificity, while biopsy-the gold standard-is invasive and impractical for multifocal lesions. The study aimed to assess the diagnostic performance of multi-phase contrast-enhanced computed tomography (CECT) in differentiating HEH from HMT.

Methods

This retrospective comparative study included 33 patients (mean age: 42.06 years; male: 27.27%) with histologically confirmed HEH and 36 patients (mean age: 64.22 years; male: 66.67%) with HMT between January 2017 and July 2024. Only non-coalescent hepatic lesions at the
