Three cases of vascular tumor of the scalp were presented. A 4-month-old girl underwent an operation for a vascular tumor of the scalp which had been noticed as a birth mark and had recently increased in size. The specimen was histologically proven to be hemangioendothelioma. The second case was an 11-year-old girl whose tumor of the scalp, having been recognized as a birth mark, had become prominent and pulsatile for the last 2 years without any history of trauma. The tumor was angiographically and histologically interpreted as cirsoid aneurysm. The third case was a 21-year-old female complaining of a pulsatile swelling at the occiput following a blunt head injury. The angiography demonstrating a complex vascular network composed of a number of feeding arteries and markedly dilated tortuous draining veins documented the origin of this tumor, cirsoid aneurysm, to be congenital and not traumatic. Cirsoid aneurysms, though occasionally located after trauma, were considered to be the development of a persistent primitive arteriovenous communication within the scalp and should be differentiated strictly from arteriovenous fistulae, which consist of a simple arteriovenous shunt caused without doubt by trauma to the head.
