Orbital hematoma

Hematoma (hematocele) is a mass composed of blood or blood products, also called hematic-cyst by the author. The literature has different interpretations of the meaning of hematoma and hematic cyst (blood cyst, hemotocele). It is generally believed that the local clustering of blood after orbital bleeding is called a hematoma; the hematoma persists for a long time and is surrounded by surrounding connective tissue, which is called a blood cyst. Lack of epithelial or endothelial cell lining within the fibrous capsule. Only hematomas lined with endothelial or epithelial cells are called blood cysts, so only venous vascular malformations, cavernous hemangiomas, lymphangiomas, and hemorrhages in skin-like cysts can form blood cysts. This accumulation of blood in the orbital region can be under the periosteum or inside the orbital. In some cases, the accumulation of intraorbital hemorrhage can produce a similar effect to a true mass.
