Figure 1
Figure 1 Preoperative computed tomography and magnetic resonance imaging images with white arrows pointing to the lesion. A: Computed tomography image showing a hypodense mass of approximately 81 mm × 83 mm in size in the liver; B and C: Enhanced scans in the arterial and delayed phases show heterogeneous enhancement of the lesion; D: Magnetic resonance imaging T1-weighted image (T1WI) shows a mixed signal with a predominantly low signal; E: T1WI enhancement with mild heterogeneous enhancement in the arterial phase; F: Diffusion-weighted imaging shows a high heterogeneous signal; G: Apparent diffusion coefficient image shows a low heterogeneous signal; H: Coronal T2WI shows a high signal with multiple iso- and low-signal divisions.

Figure 3 Computed tomography images with white arrows pointing to the lesions. A: Computed tomography (CT) on October 8, 2021 showed a new mass of approximately 53 mm × 25 mm in the right lobe of the liver; B and C: Magnetic resonance imaging on the same day; D and E: CT on November 24, 2021 showed an enlarged and increased intrahepatic lesion.
