The liver is the most common organ involvement in diffuse neonatal hemangiomatosis, and its involvement can be determined through imaging and presence of hepatomegaly, or enlarged liver. [6] The multiple lesions on the liver cause arteriovenous shunts, causing high-output heart failure and pulmonary hypertension as compensation.
A hemangioma can occur anywhere on the body, but most commonly appears on the face, scalp, chest or back. They tend to grow for up to a year before gradually shrinking as the child gets older. A hemangioma may need to be treated if it interferes with vision or breathing or is likely to cause long-term disfigurement.
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus. [6] and formerly known as a cavernous hemangioma.
Cavernous hemangiomas (also called hepatic hemangioma or liver hemangioma) are the most common type of benign liver tumor, found in 3%– 10% of people. [2] They are made up of blood clusters that are surrounded by endothelial cells. [5] These hemangiomas get their blood supply from the hepatic artery and its branches. [5]
A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.

Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
Histology must be used to make the diagnosis because the tumor may be hard to differentiate from other neoplasms with similar characteristics. [7] Histologically, hemangiopericytoma is characterized by staghorn-shaped blood vessels and sponge-like sinusoidal vasculature that are randomly linked and encircled by ovoid, short spindle-shaped cells.
