Abstract
OBJECTIVE
We report here on two cases of pseudoaneurysms that were diagnosed using computed tomographic angiography (CTA), with one arising in the superficial temporal artery and the other arising in the occipital artery.
METHODS
Case 1: A 29-year-old man presented with a slow growing, pulsatile mass on the left side of his forehead following a blow from a fist 10 days earlier. CTA revealed an 11 x 8 x 11-mm oval pseudoaneurysm arising from the frontal branch of the left superficial temporal artery. Case 2 : A 36-year-old man presented with a pulsatile mass in the right suboccipital region that had been present for the past year. He had no history of direct trauma. CTA revealed a 15 x 8 x 13-mm oval dye-filled sac arising from the right occipital artery.
RESULTS
Based on the CTA images, the parent arteries were exposed and ligated proximally and distally to the pseudoaneurysms and then they were completely excised.
CONCLUSION
CTA is a minimally invasive technique for making the diagnosis of scalp pseudoaneurysms and CTA is also useful for the preoperative planning.
