Ans. A. Hemangioma
- These tumours are slow growing and are generally asymptomatic unless they exert mass effect on sensitive structures. Occasionally they may present as a swelling or a palpable mass, especially in the skull. When large and strategically located they may present with a pathological fracture.
- If they are high-flow lesions, shunt-related symptoms may also be present.
- Primary intraosseous haemangiomas are slow growing vascular neoplasms, usually located in the medullary cavity. They are classified as benign, but rarely may be locally aggressive.
- Histologically, intraosseous haemangiomas demonstrate hamartomatous vascular tissue within endothelium, but may also contain fat, smooth muscle, fibrous tissue, and thrombi.
