Küçük damar hastalığı zemininde gelişen Percheron arter sulama alanı infarktı; önemli MRG bulguları

Abstract

Occlusion of a variant artery ‘artery of Percheron’ causing bilateral paramedian thalamus and usually rostral midbrain infarct is infrequent in addition presentation of clinicial findings of this entity is rapid and dramatic. Therefore this scene must be recognized immediately in order to route the patient for adequate treatment. Bilateral thalamic infarcts emerge from oclussion of either arterial or venous vessels. Discrimination of underlying cause or type of occlusion not only provides appropriate treatment but also predicts prognosis of the patient. As clinical scene is wide and cumbersome for management of patient, imaging findings particularly magnetic resonans (MRI) and diffusion weighted imaging (DWI) play a key role at this point. Here in authors reported two cases of artery of Percheron infarct due to possible small vessel disease emphasising significant MRI and DWI findings in two cases and discussed clues for differential diagnosis according to literature.
