Interest of contrast-enhanced sonography to identify focal nodular hyperplasia with sinusoidal dilatation

Abstract

CEUS seems to be an essential step for the diagnosis of non-typical FNH, such as FNH-sd. This small series highlights the interest of performing both CEUS and MRI for the diagnosis of atypical focal liver lesions, such as FNH-sd.

Focal Nodular Hyperplasia of the Liver: Contrast‐Enhanced Ultrasonographic Features With Sonazoid

“…In this study, 23 of 31 focal nodular hyperplasia lesions (74.2%) showed typical vascular patterns, including central stellate vascularity and centrifugal enhancement. These typical vascular patterns on CEUS have been well documented in previous studies, with a wide range of detection rates from 30% to 100% . Among these studies, Luo et al reported sensitivity of 82% for “diffuse enhancement with spoked‐wheel arteries” with Sonazoid, using intermittent scanning with a high mechanical index.…”

“…Recent studies have reported that CEUS can provide valuable information about the central feeding artery, spoked‐wheel vascularity, and the centrifugal filling pattern of focal nodular hyperplasia, which can lead to a confident diagnosis. However, most studies have been conducted with a contrast agent other than Sonazoid.…”
