The angiographic recognition of displacement of the meningeal branch of the anterior or posterior ethmoidal artery of the ophthalmic artery system—a sign not previously reported in the literature—led to the correct preoperative diagnosis of frontal epidural hematoma in 2 patients with frontal head injury.

Furthermore, the validity of the sign is strengthened by its absence in a third patient, who also sustained anterior polar brain trauma, otherwise demonstrated classical angiographic manifestations of post-traumatic frontopolar cerebral edema, and recovered without craniotomy.

The differential diagnosis of anterior polar space occupying lesions of traumatic origin is reviewed.
