Abstract

We report the case of a 73-year-old woman who presented with right VI nerve palsy and homolateral atypical trigeminal neuralgia; standard neuroradiological investigation of orbital/retroorbital regions and intracranial arteries excluded the most commonly demonstrable underlying causes while brain magnetic resonance (T1-weighted fat suppression; T2-weighted thin-section) and magnetic resonance angiography disclosed the evidence of “double” neurovascular conflict because of persistent trigeminal artery with aneurysmal dilation.

A role of this almost rare vascular condition in causing painful ophthalmoplegia is discussed.
