Cranial arteriovenous hemangioma in a neonate.

Benign hemangiomas and vascular malformations are the most common tumor of infants and children [1]. Skull involvement is rare compared with soft-tissue involvement. A plethora of classifications applied to these lesions has led to an imperfect and suboptimal understanding of them. Burrows et al. [2] describe angiographic differences between hemangiomas and vascular malformations that corroborate clinical and laboratory differences previously reported. Enzinger and Weiss [1] state that arteriovenous hemangioma as a specific entity bridges the distinct categories of vascular malformation and hemangioma, often exhibiting features of both lesions. We report a rare neonatal cranial arteriovenous hemangioma with elements of both hemangioma (dense angiographic stain) and vascular malformation (osseous irregularity and calcified phleboliths).
