Cirsoid aneurysm of scalp is a rare arteriovenous malformation (AVM) of external carotid branches and scalp veins. This malformation of scalp is also synonymously called as plexiform angioma, aneurysma racesomsum, and aneurysm cirsoide, aneurysma serpentinum. This AVM can be congenital or acquired; a congenital form will be present at birth, however, becomes overt only after puberty. Superficial temporal artery is the feeder in approximately 70-80% of the cases, followed by occipital and supraorbital artery. Multidetector computed tomography angiography reconstructed images can provide excellent detail of the feeders, draining veins and their soft tissue relations. Volume rendering data sets in computer workstations we can actually perform virtual dissection layers of the lesion for operative planning. Well planned surgical excision can have least surgical recurrence rates and complications
