PRIMARY HEMANGIOMA OF THE SKULL

CASE REPORT OF AN UNUSUAL TUMOR

¹ Director of Radiology Services, Orange County General Hospital, Orange, California
² Director of Pathology
³ Director of Neurosurgery

Primary hemangioma of the skull, a relatively rare tumor, is reported. This tumor occurs in approximately 0.2 per cent of osseous neoplasms. The characteristic roentgenologic features, namely, a typical honeycomb appearance and a pathognomonic "sun ray" appearance are described.

Usually, these neoplasms are rounded, sharply defined, surrounded by a halo of decalcification and, generally, there is no surrounding sclerotic bone reaction.

The case presented is unusual in that, instead of the characteristic external subcutaneous expansion, there was predominantly extensive intracranial expansion with absence of clinical neurologic symptomatology.
