Isolated bilateral lateral geniculate infarction producing bow-tie visual field defects.
METHODS
We examined a unique case of stroke in a 29-year-old woman. Magnetic resonance imaging revealed isolated bilateral acute infarctions of the lateral geniculate bodies (LGB). Visual field testing demonstrated incongruous but homonymous bilateral visual field loss in a bow-tie configuration.


CONCLUSIONS
Isolated bilateral damage to the LGB is a rare event. Literature review has revealed only 4 previous incidents of bilateral damage to both LGB. We present a literature review and a case of bilateral LGB infarction producing visual field defects suggestive of bilateral lateral choroidal artery involvement in an individual with classic migraine.
