title: Trigeminal hypoplasia due to vertebrobasilar dolichoectasia: A new entity.
abstract: The term "vertebrobasilar dolichoectasia" refers to anomalous dilatation of the intracranial arteries associated with elongation or tortuosity of the affected vessels. The etiology of the disease is unknown and is usually detected incidentally. The predominant clinical manifestations arise due to the mass effect of the dilated vessels and may include cranial nerve compression, extrinsic aqueductal compression, motor and sensory disturbances. Trigeminal hypoplasia is a very uncommon condition, usually described in association with Goldenhar-Gorlin syndrome and has not yet been attributed to vertebrobasilar dolichoectasia. The current case report highlights this rare association of trigeminal nerve hypoplasia and vertebrobasilar dolichoectasia, leading to hemifacial and corneal anesthesia.
