case_images: Abdominal CT shows a lobulated, heterogenous contrast enhancing, soft tissue mass involving the entire left hepatic lobe (10x7 cm). Note the focal nodular enhancement around the peripheral portion of the hepatic mass in arterial phase.

case_images: The tumor showed focal nodular enhancement around the peripheral portion of the hepatic mass during the arterial phase, and an increased extent of peripheral nodular contrast-enhancement with a persistent low density noncontrast-enhancing portion in the center of the tumor during the delayed phase (Fig. 1, 2).
case_images: Abdominal CT shows an increased extent of peripheral nodular contrast-enhancement with a persistent low density noncontrast-enhancing portion of the tumor centrally in delayed phase.

case_images: The tumor showed focal nodular enhancement around the peripheral portion of the hepatic mass during the arterial phase, and an increased extent of peripheral nodular contrast-enhancement with a persistent low density noncontrast-enhancing portion in the center of the tumor during the delayed phase (Fig. 1, 2).
case_images: Angiography shows some tumor-supplying arteries from the left hepatic artery. There is no evidence of gross invasion in the main arteries.

case_images: The angiography illustrated some tumor supplying arteries from the left hepatic artery, with no evidence of gross invasion to the main arteries (Fig. 3).
case_images: MRCP shows no dilatation of intra- and extra-hepatic bile duct. The left intrahepatic duct is not visualized due to tumor replacement.

case_images: The left intrahepatic duct was not visualized, probably due to tumor replacement (Fig. 4).
case_images: The specimen shows an inhomogeneous, multinodular mass with a focal necrosis.

case_images: No major vessel invasion was observed (Fig. 5).
case_images: H-E stained microscopic specimen (x40). The thrombotic material is fragmented and entrapped by the ingrowing endothelial cells. There is no soft tissue invasion, atypia, or significant necrosis.

case_images: There was no soft tissue invasion, atypia, or significant necrosis, which collectively supported the diagnosis of intravascular papillary endothelial hyperplasia (Masson's hemangioma) of the liver (Fig. 6).
