Imaging FNH with CEUS on Toshiba Aplio

Focal nodular hyperplasia (FNH) is a benign tumour-like mass of the liver, second only to cavernous haemangiomas in frequency. It has characteristic radiographic features in multi-modality imaging, but some lesions may be atypical in appearance. FNH are usually treated conservatively.

Contrast-enhanced ultrasound tell signs:

Arterial phase
FNH will enhance relative to background liver
Prominent feeding vessel may be seen

Portal venous phase
Centrifugal filling (opposite to haemangioma and adenoma)
Sustained enhancement in the portal venous phase (opposite to adenoma)
Unenhanced scar may be present
