Conventional Hemangioma and Lymphangioma

Hemangioma of the bone is a benign neoplasm of endothelial cells that form blood vessels. It is one of the most common tumors of bone and has been found in vertebral bodies in approximately 10% of the adult population. The lesions can be classified according to their morphology and number. They include conventional capillary or cavernous hemangioma, diffuse cystic angiomatosis, and hemangioma/lymphangioma with massive osteolysis (Gorham-Stout syndrome, aka disappearing bone disease). Conventional hemangioma is often asymptomatic and is more frequent in adult women. Vertebral bodies are the most common location, followed by the craniofacial bones and metaphyses of long bones. Imaging of hemangioma is characterized by coarse trabeculations. Asymptomatic lesions may not require treatment. Prognosis is excellent
