Figure

• 

  Fig. 1 Abdominal computed tomography demonstrated irregular-shaped, lobulated mass (approximately 9 cm) at the right rectus abdominis muscle. The tumor shows (A) low attenuation in the precontrast phase, (B) enhancement in the arterial phase, and (C) wash out in the delayed phase. (D) Tumor thrombus was found in the umbilical vein (arrow).

• 

  Fig. 2 (A, B) Positron emission tomography-computed tomography findings. Hypermetabolic mass lesion was noted in the right rectus abdominis muscle. Otherwise, no definite abnormal hypermetabolic lesion was found on the torso image.

• 

  Fig. 3 (A) Ultrasonography showed abnormal lobulating contoured heterogeneous echoic mass in the periumbilical portion of the wall, measured 9×5.5 cm. (B) The mass revealed hypervascularity at color doppler imaging.

• 

  Fig. 4 Pathologic gross finding shows well-defined, multinodular mass with gray/tan color and focal necrosis. Tumor thrombus in the blood vessel was found (arrow).

• 

  Fig. 5 Microscopic findings demonstrating a trabecular pattern, polygonal-shaped tumor cells with eosinophilic cytoplasm, and mild to moderate nuclear atypia, suggesting well to moderately differentiated hepatocellular carcinoma (H&E, ×100).
