Radiological aspects of giant hepatocellular adenoma of the left liver: A case report

Figure 1 Hepatocellular adenoma on computed tomography scans. A: Unenhanced scan; B: Arterial phase of contrast-enhanced scan. A feeding artery was visible on the verge of the tumor (arrow); C: Portal phase of contrast-enhanced scan.

Figure 2 Hepatocellular adenoma on magnetic resonance imaging scans. A: T1-weighted image. The fibrous capsule of the tumor was clearly visible (arrow); B: T2-weighted image; C: Diffusion-weighted imaging; D: Arterial phase of contrast-enhanced scan. Feeding arteries were visible on the verge of the tumor (arrow); E: Delayed phase of contrast-enhanced scan. The fibrous capsule of the tumor was markedly enhanced (arrow); F: Multiplanar reconstruction.
