von Willebrand Disease Associated with Superficial Temporal Artery Pseudoaneurysm

We report on two patients with von Willebrand disease (vWD) that presented with superficial temporal artery pseudoaneurysms following minor blunt trauma. We discuss the possible pathophysiological link between vWD and blood vessel abnormalities. The cases highlight the importance of considering the diagnosis of vWD in patients presenting with pseudoaneurysm.
