EnglishThe artery of Percheron is a rare anatomical variant where a single thalamic perforating artery arises from the proximal posterior cerebral artery (P1 segment) between the basilar artery and the posterior communicating artery and supplies the rostral mesencephalon and both paramedian territories of the thalami. Almost one third of human brains present this variant. Occlusion of the artery of Percheron mostly results in a bilateral medial thalamic infarction, which usually manifest with altered consciousness (including coma), vertical gaze paresis and cognitive disturbance. The presentation is similar to the ‘top of the basilar syndrome’ and early recognition should be prompt. We describe the case of a young female with this vessel variant that experienced a bilateral thalamic stroke. On magnetic resonance angiography bilateral thalamic infarcts and a truncated Artery of Percheron was demonstrated. Occlusion of the vessel was presumably due to embolism from a patent foramen ovale. Thrombolysis was performed with incomplete symptoms remission, cognitive impairment and speech disorders persist. Early recognition and treatment of posterior circulation strokes is mandatory and further investigation for underlying stroke aetiologies are needed.

| Abstract: | The artery of Percheron is a rare anatomical variant where a single thalamic perforating artery arises from the proximal posterior cerebral artery (P1 segment) between the basilar artery and the posterior communicating artery and supplies the rostral mesencephalon and both paramedian territories of the thalami. Almost one third of human brains present this variant. Occlusion of the artery of Percheron mostly results in a bilateral medial thalamic infarction, which usually manifest with altered consciousness (including coma), vertical gaze paresis and cognitive disturbance. The presentation is similar to the ‘top of the basilar syndrome’ and early recognition should be prompt. We describe the case of a young female with this vessel variant that experienced a bilateral thalamic stroke. On magnetic resonance angiography bilateral thalamic infarcts and a truncated Artery of Percheron was demonstrated. Occlusion of the vessel was presumably due to embolism from a patent foramen ovale. Thrombolysis was performed with incomplete symptoms remission, cognitive impairment and speech disorders persist. Early recognition and treatment of posterior circulation strokes is mandatory and further investigation for underlying stroke aetiologies are needed. |
