Imaging features and management of focal liver lesions

Figure 6 Hepatic cyst. A: Ultrasound shows an anechoic well-defined lesion (arrow) with a single thin septation (arrowhead); B: Axial non-contrast computed tomography (CT) image demonstrates a hypodense lesion (arrow); C: Axial contrast-enhanced CT image in the portal venous phase shows a hypodense lesion (arrow) with no enhancement; D: Axial T2-weighted magnetic resonance imaging (MRI) shows a markedly hyperintense lesion (arrow); E: Axial T1-weighted MRI shows a hypointense lesion (arrow); F: Axial T1-weighted MRI with an extracellular gadolinium-based contrast agent in the portal venous phase shows the lesion (arrow) with no enhancement.
