Isolated bilateral lateral geniculate infarction producing bow-tie visual field defects

Case report: 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 configuratio...

Description
Summary:Case report: 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. Comments: 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. Observation: Nous avons examiné un cas unique d’accident cérébrovasculaire chez une femme de 29 ans. L’imagerie par résonance magnétique (IRM) a révélé des infarctus bilatéraux et isolés en phase aiguë des corps genouillés latéraux (CGL). Le test du champ visuel a démontré une perte incongrue mais homonyme du champ visuel dans la configuration «bow-tie». Commentaires: Le dommage bilatéral isolé aux CGL est rare. Une revue de la littérature n’a révélé que 4 incidents antérieurs de dommages bilatéraux aux deux CGL. Nous présentons une revue de la littérature et un cas d’infarctus des CGL source de défauts du champ visuel, indiquant la possibilité d’implication bilatérale de l’artère choroïdien latéral chez une personne ayant une migraine classique.
