Percheron artery infarct (PAI) is uncommon clinically.One case had an acute onset of coma,impaired left limb activities,verbal incoherence,drinking cough and vertical gaze palsy after regaining consciousness.Magnetic resonance imaging (MRI) showed symmetrical high signal intensity on diffusion-weighted imaging (DWI) in bilateral paramedian thalami and a distinct pattern of V-shaped midbrain hyperintensity on DWI.Magnetic resonance angiography (MRA) showed left-sided embryonal posterior cerebral artery (PCA) from ipsilateral internal carotid artery (ICA).Systemic treatment yielded a poor prognosis.
