좌측 후두엽-측두엽의 경색으로 인해 발생한 Balint 증후군 1예

Abstract

Balint syndrome, first described by Balint in 1909, is a triad of visual perceptual difficulty including optic ataxia, ocular apraxia, and simultanagnosis. These three clinical symptoms are related to lesions in the partieto-occipital lobe in which cerebral infarction is the most common cause that has been reported. We described a patient that had symptoms consistent with Balint syndrome where a cerebral infarction in both parieto-occipital lobes did not exist. A 68-year-old man presented with sudden development of right-sided weakness. Although the patient displayed the classical clinical triad in Balint syndrome, a brain MRI illustrated an infarction in the medial portion of left temporo-occipital lobe and in the left thalamus.
