Duplicated middle cerebral artery

Dr Mark Thurston and Dr Bruno Di Muzio et al.

The duplicated middle cerebral artery is an anatomical variant in which there are two middle cerebral arteries originating from the distal end of the internal carotid artery.

Supply

The duplicated artery supplies the anterior temporal lobe.

Differential diagnosis

It should not be confused with an accessory middle cerebral artery, where the anomalous duplicated vessel originates from the anterior cerebral artery.
