Traumatic aneurysm of superficial temporal artery. CT demonstration.

A case of traumatic pseudo-aneurysm of the superficial temporal artery documented on Computed tomography (CT) and angiography is described in a 55-years-old female, who was treated by surgical excision. Computed tomographic appearance of this lesion is illustrated. This represents, to our knowledge, the first CT demonstration of traumatic aneurysm of superficial temporal artery within a large subgaleal haematoma.
