# Sarcomatoid hepatocellular carcinoma mimics hepatic abscess on contrast‐enhanced ultrasound

## TL;DR

A rare liver cancer called sarcomatoid hepatocellular carcinoma can look like a liver abscess in imaging tests, making it hard to diagnose correctly.

## Contribution

This case highlights how SHCC can mimic a hepatic abscess using contrast-enhanced ultrasound and CT scans.

## Key findings

- SHCC was misidentified as a hepatic abscess using imaging techniques.
- The diagnosis was confirmed only after pathological examination.
- SHCC has both epithelial and mesenchymal tumor features.

## Abstract

Sarcomatoid hepatocellular carcinoma (SHCC) is a rare subtype of hepatocellular carcinoma characterized by abdominal pain or persistent fever with an inflammatory reaction. Here, we report a case of SHCC mimicking hepatic abscess described by not only ultrasonography but also computer tomography. SHCC is a rare subtype of hepatocellular carcinoma characterized by epithelial and mesenchymal tumor features with sarcomatoid morphology. Here, we report a case of SHCC described by ultrasonography and computer tomography as well as confirmed by pathological examination.

A 71‐year‐old male patient with a mass located in the liver was described by imaging, including routine abdominal ultrasound, contrast‐enhanced ultrasound, plain computer tomography, and enhanced computer tomography. A diagnosis of sarcomatoid hepatocellular carcinoma (SHCC) was confirmed by pathological examination.
