Abstract:
A 2-year-old girl presented with cutaneous facial, palpebral, back, perianal, and perineal hemangiomas and a subcutaneous neck and parotid voluminous hemangioma, associated with several extracranial vascular abnormalities, such as the absence of the ipsilateral internal carotid artery and hypoplasia of the common carotid arteries. Both vertebral arteries showed an embryonic appearance, without completing their maturation and without obliteration of all the right and left longitudinal neural arteries.
