Abstract: Cavernoushemangioma of the skull is a rare benign tumor of the skull.It usually has no typical clinical manifestations or only presents with focal tenderness.Occasionally,headache,nerve dysfunction and epilepsy can be seen.Head CT showed local swelling or lytic lesions with reduced internal density and sparse bone trabeculae,which was easily misdiagnosed as eosinophilic granuloma of the skull.The risk of intraoperative hemorrhage in cavernous hemangioma of skull is high,so preoperative differential diagnosis is very important.

Key words: cavernous hemangioma; eosinophilic granuloma; cranioplasty
