Intraorbital cavernous hemangioma

Cavernous hemangioma is named for the cavernous sinus cavity in the tumor. It is the most common tumor in the orbit that occurs in adults, accounting for 10% to 23% of intraorbital tumors. Women are more common than men. The disease is a congenital hamartoma. The tumor consists of sinusoids and fibrous spaces of varying sizes, with a complete envelope. Due to the slow growth of tumors, it is often found after adolescence due to exophthalmos. It was thought that cavernous hemangioma was caused by increased intraluminal cavity pressure and luminal dilatation of capillary hemangioma, but neither the clinical nor pathological evidence could prove a causal relationship between the two. Because smooth muscle cells are found in the blood vessel wall, according to the development process of blood vessels, they belong to tumors with more mature angiogenesis after capillaries.
