Abstract
Primary intraosseous hemangiomas are benign, vascular malformations that account for
approximately 1% of all primary bone neoplasms. These tumors are mostly found in vertebral
bodies and are rarely seen in the calvarium, where they represent 0.2% of bony neoplasms.
When found in the skull, they tend to present with vague symptoms and do not have
the typical radiological findings suggestive of hemangiomas. Because of this, these
tumors can be missed in many cases or may be misinterpreted as more ominous lesions
like multiple myeloma or osteosarcoma. Involvement of the skull base is exceedingly
rare, and presentation with cranial nerve unilateral polyneuropathies has not been
reported. We report a patient case with review of recent pertinent literature.
