Intraosseous Hemangioma of Skull
- Intra-osseous hemangiomas are benign vascular lesions of the bones. These lesions are most frequently seen in the vertebral column and the calvaria, particularly in the parietal and frontal bones. Histologically, hemangiomas are classified as capillary, cavernous, or mixed types.
- Such hemangiomas are often found as incidental findings, with a predilection for middle-aged women.
- Key Diagnostic Features: Well-circumscribed, expansile intraosseous lytic lesion with intact inner and outer skull tables in a honeycomb, sunburst or soap-bubble like appearance. Usually expansion of the outer skull table is more than the inner table.
- DDx: Fibrous dysplasia, Paget's disease, metastases, lymphoma
- Rx: Surgical excision if symptomatic
