case_images: As shown in  Figure 1 , a computed tomography (CT) scan performed at the time of her presentation showed a solitary hepatic mass measuring 160 mm x 110 mm, with no other nodules.
case_images: (A) Initial computed tomography (CT) scan of the abdomen showing a 160 mm x 110 mm hepatic mass with no daughter nodules in the other hepatic lobe or tumoral thrombosis in the inferior vena cava and right atrium; (B) Tumor mass is reduced to 37 mm x 31 mm following neoadjuvant treatment; (C, D) CT and magnetic resonance imaging reveal post-treatment changes in the junctional area of the left and right lobes of the liver with no recurrent lesions.

case_images: On December 20, 2022, CT and magnetic resonance imaging scans revealed post-treatment changes of HCC in the junctional area of the left and right lobes of the liver ( Figures 2C, D ).
case_images: Dose-planning of radiotherapy. Planned target volume (GTV: red, PTV1: blue) covered by the 95% isodose can be seen in (A) axial, (B) coronal, and (C) sagittal planes on pretreatment planning computed tomography. (D) Dose-volume histogram shows that 95% of the PTV volumes irradiated with more than 5000 cGy.
