Cavernous hemangioma of the skull in a neonate.

Cavernous hemangiomas rarely occur in the calvarium and most commonly present in middle-age. Although a congenital vascular disorder can theoretically cause a diploic lesion in any age group, a calvarial cavernous hemangioma has not been reported in newborn. A 4-month-old male infant presented with a large left parietal mass that had been present since birth. Total resection was performed. Pathological examination revealed a cavernous hemangioma developing within the diploic space adjacent to prior hemorrhages. Surgery was performed in this case because of the size and persistence of the lesion. Removal of tumors of a benign nature from the calvarium can be done safely. Cavernous hemangioma of the skull in a neonate should be considered as one of the differential diagnoses in the case of suspected ossified cephalohematoma.
