Bottom Line: In 1923, Masson regarded this disease as a neoplasm inducing endothelial proliferation, however, now it is considered to be a reactive vascular proliferation following traumatic vascular stasis.The lesion has a propensity to occur in the head, neck, fingers, and trunk.Occurrence within the abdominal cavity is known to be very rare, and especially in the liver, there has been no reported case up to date.

ABSTRACT
Intravascular papillary endothelial hyperplasia (Masson's hemangioma) is a disease characterized by exuberant endothelial proliferation within the lumen of medium-sized veins. In 1923, Masson regarded this disease as a neoplasm inducing endothelial proliferation, however, now it is considered to be a reactive vascular proliferation following traumatic vascular stasis. The lesion has a propensity to occur in the head, neck, fingers, and trunk. Occurrence within the abdominal cavity is known to be very rare, and especially in the liver, there has been no reported case up to date. The authors have experienced intravascular papillary endothelial hyperplasia of the liver in a 69-yr-old woman, and report the case with a review of the literature.

MRCP shows no dilatation of intra- and extra-hepatic bile duct. The left intrahepatic duct is not visualized due to tumor replacement.

Figure 4: MRCP shows no dilatation of intra- and extra-hepatic bile duct. The left intrahepatic duct is not visualized due to tumor replacement.

Mentions: Abdominal CT scan showed a 10×7 cm-sized, lobulated, heterogenous contrast enhancing, soft tissue mass involving the entire left hepatic lobe. 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). The angiography illustrated some tumor supplying arteries from the left hepatic artery, with no evidence of gross invasion to the main arteries (Fig. 3). MRCP (magnetic resonance cholangio-pancreatogram) revealed no dilatation of the intrahepatic duct or the common bile duct. The left intrahepatic duct was not visualized, probably due to tumor replacement (Fig. 4).
