Abstract (2. Language): 
We report a 52 years old male patient who developed acute onset diplopia and vertigo. Neurological examination revealed combined upward and donward gaze palsy and his MRI scan displayed a small unilateral lesion in the right midbrain. The lesion is presumed to have interrupted the pathways involved in vertical gaze palsy just before decussation producing a functionally bilateral lesion. In this case, we would like to question whether there is a right sided dominance in the pathways controlling the vertical gaze.
Abstract (Original Language): 
Bu olgu sunumunda ani baĢlangıçlı diplopi ve vertigo yakınmaları olan 52 yaĢında bir erkek hasta bildirilmiĢtir. Nörolojik muayenesinde yukarı ve aĢağı bakıĢ paralizisi saptanan hastanın kranial MR görüntülemesinde, sağ mezensefalonda küçük, tek taraflı bir lezyon izlendi. Bu lezyonun, vertikal bakıĢı ilgilendiren yolakları, çaprazlaĢmadan hemen önce engelleyerek fonksiyonel olarak bilateral klinik bulgulara yol açtığı düĢünüldü ve vertikal bakıĢı düzenleyen yolaklarda sağ taraf baskınlığının olup olmadığı tartıĢıldı.
