# B-mode and contrast-enhanced ultrasound versus magnetic resonance imaging in hepatic angiomyolipoma: a case report

## TL;DR

This case report compares ultrasound and MRI in diagnosing a rare liver tumor in a patient with a genetic condition.

## Contribution

The study highlights the diagnostic value of B-mode and contrast-enhanced ultrasound in hepatic angiomyolipoma.

## Key findings

- B-mode and contrast-enhanced ultrasound correctly identified a benign hepatic lesion.
- MRI initially suggested hepatocellular carcinoma, but ultrasound findings were confirmed by histology.
- HAML is rare and can be challenging to diagnose, but ultrasound may aid in accurate assessment.

## Abstract

Angiomyolipoma is a solid mesenchymal tumour that usually affects the kidney. Hepatic localization of angiomyolipoma (HAML) is rare and usually asymptomatic however it presents a challenging differential diagnosis. We present the case of a 45-year-old man affected by tuberous sclerosis complex type 2 (TSC2) and an hepatic lesion suspected to be hepatocellular carcinoma on magnetic resonance but whose Bmode ultrasound and contrast-enhanced ultrasound (CEUS) findings were consistent with benignity, as confirmed by histology.
