Summary:

Description	Radiopaedia case ID: 21641 Image ID: 2917351 Plane projection: 1 min 45 s post-injection Study description: Contrast-enhanced ultrasound Study findings: Dynamic images of the segment VI lesion following intravenous injection of 2ml SonoVue® (sulphur hexafluoride microbubbles). Dynamic images demonstrate avid arterial enhancement commencing approximately 11 s post injection of contrast. The first 4-5 s of the clip clearly show a centrifugal, i.e. 'inside-out' pattern of enhancement. Select still images show equilibrium with liver parenchyma; there is no washout. The lesion is more difficult to see on the control B-mode image on the right hand side during portal venous phase because microbubbles present within the vascular spaces of the lesion are also visible on B-mode. Modality: Ultrasound System: Hepatobiliary Findings: There is a 1.35 cm sharply circumscribed rounded lesion in segment VI of the liver. The lesion has a hypoechoic rim. No color Dopper signal was detected within. Surrounding liver parenchyma is normal in appearance.
