A pseudoaneurysm is an uncommon pathology arising from any artery in the human body. It typically presents as a pulsatile swelling in contact with a blood vessel. Of pseudoaneurysms of the head and neck region, the most common site is the superficial temporal artery while that of the dorsal nasal artery is extremely rare. A pseudoaneurysm can be routinely diagnosed by its clinical features and confirmed by radiologic evaluation. The authors report a case of pseudoaneurysm of the dorsal nasal artery, which was misdiagnosed as a hematoma owing to its non-pulsatile nature during initial presentation.
