Bilateral Superior Altitudinal Hemianopia due to Bilateral Occipital Lobe Infarction

ABSTRACT

We report a 77-year-old man showing bilateral superior altitudinal hemianopia (BSAH) caused by bilateral occipital lobe infarction. The lesions existed into the lingual gyri and involved V1, V2 and V3 in the visual cortex on both sides. The location of the lesions correlated well with visual field defects in our patient. There have been 8 case reports of BSAH caused by occipital lobe lesions, however, the extent of the lesions inside the visual cortex was not evaluated in the previously reported patients. The analysis in our patient showed a close clinico-radiological correlation of BSAH.
