Cavernous Hemangioma - Causes, Symptoms & Treatment

Cavernous Hemangioma Alternate Names is Strawberry Nevus. Cavernous hemangioma is the most common primary liver tumor. The tumor usually rests inside the extraocular muscle cone (that space immediately behind the eye surrounded by the muscles which move the eye). Cavernous hemangioma is a vascular tumor, which contains stagnant blood. If the tumor causes compression of the optic nerve with associated peripheral vision loss or other signs of optic nerve compromise, the tumor must usually be excised. Cavernous hemangioma arises from the endothelial cells that line the blood vessels and consists of multiple, large vascular channels lined by a single layer of endothelial cells and supported by collagenous walls. They are frequently asymptomatic and incidentally discovered at imaging, surgery, or autopsy

Cavernous Hemangioma are probably congenital in origin. Cavernous hemangiomas may develop secondary infections and ulcerate. Bleeding is common and may be significant following injury to the hemangioma.Hereditary factors may play a role in the pathogenesis of some familial forms. The vast majority of hemangiomas (as many as 85%) are asymptomatic. Hemangiomas may cause symptoms because of the compression of adjacent structures, rupture, acute thrombosis, or consumptive coagulopathy (Kasabach-Merritt syndrome). Hemangiomas can occur in individuals of any age. They frequently occur in middle-aged women. Large cavernous hemangiomas distort the skin around them and will ultimately leave visible changes in the skin. Superficial capillary hemangioma may involute completely, leaving no evidence of its past presence.
