Abstract:
An 83-year-old man reported falling and bumping his right lateral forehead on the ground 3 weeks previously. Physical examination revealed a soft, reddish swelling on the lateral forehead. Computed tomography confirmed a hematoma of the right lateral forehead. On the seventh hospital day, the swelling showed slight enlargement. Re-examination revealed a pulsatile mass with a palpable thrill and systolic bruit. Doppler echo showed pulsation of the swelling, which disappeared with compression of the anterior branch of the superficial temporal artery (STA). Surgical exploration was performed, and the pseudoaneurysm was resected. Pathological findings confirm a pseudoaneurysm.
