Case Discussion
Cirsoid aneurysms are rare arteriovenous malformations of the scalp which commonly occur due to arteriovenous shunts, within the scalp, between the external carotid artery and the scalp veins
The superficial temporal artery is the vessel most involved, while the occipital artery is less frequently.
