Multifocal osteolytic lesions of the skull: a primary cavernous hemangioma mimicking a neoplastic invasive lesion

Intraosseous cavernous hemangioma is a rare cause of osteolytic lesions of the skull, and its multifocal type is even more infrequent. This tumor is difficult to accurately diagnose by imaging and can be confused with osteolytic Langerhan's cell histiocytosis or other neoplasms. Here we present a case of multifocal intraosseous cavernous hemangioma of the skull treated with surgical intervention in our hospital five years ago. A review of related literatures and case reports is also provided to help clarify the diagnosis and devise treatment regimens. In light of the difficulties of early diagnosis, early en bloc surgical removal is recommended.
