Three cases of bilateral paramedian thalamus ischemia consistent with the occlusion of the artery of Percheron were indentified in our department between 11/2016 and 11/2017. In the first case, it was a 48-year-old woman investigated for mild alteration of conciousness and desorientation in place and time. In the second case, it was a 51-year-old man presenting with uncousciousness and intermittent tonic-clonic seizures. In the third case, it was a 56-year-old man primary examined for subarachnoid haemorrhage (SAH) with known aneurysm at the tip of the basilar artery. Patient was treated by stenting of the left posterior cerebral artery and sac embolisation. In the last patient, mydriasis of left eye, alternating disturbance of consciousness and CT finding of bilateral medial thalamic ischemia developed on the following day after the endovascular intervention.
