case_images: Contrast-enhanced CT of the abdomen. A mass with contrast effect is seen in the S7 area of the right lobe of the liver (arrow), which was suspected to be hepatocellular carcinoma. The maximum diameter of the tumor is 27 mm.

case_images: As soon as she was transferred to the Gastroenterology Department, progression of FALD was suspected on echosonography, and then contrast-enhanced computed tomography (CT) performed as the first screening showed a contrast-enhanced mass lesion in the S7 area of the liver (Figure 1).
case_images: Findings of preoperative cardiac catheterization at 28 years of age. Cardiac index = 3.08 L/min/m2, pulmonary blood flow/systemic blood flow ratio (Qp/Qs) =1.02, pulmonary vessel resistance = 0.94-1.42 Um2 (Wood units), pulmonary artery index = 152.. INN: innominate vein, LSVC: left superior vena cava, LPA: left pulmonary artery, PCW: pulmonary capillary wedge pressure, RPA: right pulmonary artery, PT: pulmonary trunk, LA: left atrium, RV: right ventricle, LV: left ventricle, Des. Ao: descending aorta, m: mean pressure value (mmHg).

case_images: Preoperative cardiac catheterization was performed, and CVP was 14 mmHg, which was the same as that at 5 years of age (Figure 2).
case_images: Appearance of the liver during surgery. The hepatic surface is irregular and plastic, and part of the liver protrudes outside the liver. The location of the tumor is indicated by a triangle.

case_images: The surface of the liver was irregular and plastic, and part of the tumor protruded outside the liver (Figure 3).
case_images: a. Pathological findings of hematoxylin and eosin staining (non-tumor site). The portal vein area is fibrotic and enlarged (arrow), and bridging fibrosis is partially observed (F3) (triangle), indicating a precirrhotic state.. b. Pathological findings of hematoxylin and eosin staining (tumor site). The histopathological diagnosis of poorly differentiated hepatocellular carcinoma is confirmed.
