An 84-year-old woman was referred to the emergency department by her general practitioner following attempted aspiration of a forehead mass. She reported a 5-week history of an expanding mass on the left temporal region following a fall with minor head trauma. The mass was associated with left facial pain and numbness.

Her medical history included atrial fibrillation and she was on warfarin. On examination there was a 4cm by 2cm pulsatile mass (see Figure 1).
