The artery\u0026nbsp;originates from the posterior wall of the\u0026nbsp;internal carotid artery between the origin of the\u0026nbsp;posterior communicating artery\u0026nbsp;and the internal carotid termination and runs lateral to the\u0026nbsp;optic tract before\u0026nbsp;curving\u0026nbsp;medially to its inferomedial surface, to curve again laterally to run along the lateral aspect of the optic tract and circumvents the\u0026nbsp;cerebral peduncles\u0026nbsp;to reach the lateral geniculate body. It traverses in the posterolateral direction above the\u0026nbsp;uncus\u0026nbsp;to enter the\u0026nbsp;choroidal fissure, at the so-called plexal point.\u0026nbsp;\u003c/p\u003e\u003cp\u003eIt supplies a seemingly disparate group of structures:\u0026nbsp;\u003c/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003edeep brain structures\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cp\u003eposterior limb\u0026nbsp;\u003ca href=\"https://radiopaedia.org/articles/internal-capsule?lang=gb\"\u003einternal capsule\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003elateral\u0026nbsp;\u003ca href=\"https://radiopaedia.org/articles/thalamus?lang=gb\"\u003ethalamus\u003c/a\u003e\u0026nbsp;including\u0026nbsp;\u003ca href=\"https://radiopaedia.org/articles/lateral-geniculate-body?lang=gb\"\u003elateral geniculate nucleus\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ca href=\"https://radiopaedia.org/articles/optic-tract?lang=gb\"\u003eoptic tract\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003elateral\u0026nbsp;\u003ca href=\"https://radiopaedia.org/articles/cerebral-peduncles?lang=gb\"\u003ecerebral peduncle\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ca href=\"https://radiopaedia.org/articles/globus-pallidus?lang=gb\"\u003eglobus pallidus\u003c/a\u003e\u0026nbsp;internus\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003etail of\u0026nbsp;\u003ca href=\"https://radiopaedia.org/articles/caudate-nucleus?lang=gb\"\u003ecaudate nucleus\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003c/ul\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003emesial temporal structures (\u003ca href=\"https://radiopaedia.org/articles/uncus?lang=gb\"\u003euncus\u003c/a\u003e)\u003c/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cp\u003ehead of\u0026nbsp;\u003ca href=\"https://radiopaedia.org/articles/hippocampus?lang=gb\"\u003ehippocampus\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003cli\u003e\u003cp\u003e\u003ca href=\"https://radiopaedia.org/articles/amygdala?lang=gb\"\u003eamygdala\u003c/a\u003e\u003c/p\u003e\u003c/li\u003e\n\u003c/ul\u003e\n\u003c/li\u003e\n\u003cli\u003e\n\u003cp\u003eintraventricular segment\u003c/p\u003e\n\u003cul\u003e\u003cli\u003e\u003cp\u003echoroid plexus of the anterior part of the temporal horns of the lateral ventricles\u003c/p\u003e\u003c/li\u003e\u003c/ul\u003e\n\u003cp\u003e\u003c/p\u003e\n\u003c/li\u003e\n\u003c/ul\u003e","id":1723,"imageUrl":"https://prod-images-static.radiopaedia.org/multiple_choice_questions/218/Square-MCQ-1024x1024.006_big_gallery.jpeg","imageAttribution":{"kind":"case","rID":24302},"imageAttributionCaseInfo":{"title":"Anterior choroidal artery infarct","contributor_name":"Frank Gaillard","contributor_param":"frank","case_rid":24302,"case_param":"anterior-choroidal-artery-infarct"},"firstQuestionPath":"/questions/1779","nextQuestionPath":"/articles/brain-arterial-vascular-territories/questions/1722","relatedArticles":[{"id":13437,"title":"Ischemic stroke","link":"/articles/ischaemic-stroke?lang=us"}],"alsoUsedIn":[{"id":763,"kind":"Course","title":"Stroke Learning Pathway - page 763","link":"https://radiopaedia.org/courses/stroke-learning-pathway/pages/763"},{"id":763,"kind":"Course","title":"Content Previews - page 763","link":"https://radiopaedia.org/courses/previews/pages/763"},{"id":2100,"kind":"Course","title":"Stroke Learning Pathway - peer review - page 2100","link":"https://radiopaedia.org/courses/stroke-learning-pathway-peer-review/pages/2100"}],"stem":"\u003cp\u003eThis infarct corresponds to which vascular territory?\u0026nbsp;\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/1723"}],"attemptsPercentages":[{"alternativeId":"8561","percentage":2},{"alternativeId":"8562","percentage":52},{"alternativeId":"8563","percentage":21},{"alternativeId":"8565","percentage":16},{"alternativeId":"8564","percentage":9}],"promptToLogin":false,"questionManager":false,"articleId":"brain-arterial-vascular-territories"}
