Wallenberg syndrome, or lateral medullar syndrome, is the clinical presentation of the infarct in the territory of posterior inferior cerebellar artery. Its signs and symptoms include vertigo, nystagmus, diplopia, ipsilateral Horner syndrome, facial ruddiness and dry skin, dysphonia, dysphagia, dysarthria, ipsilateral loss of gag reflex, ipsilateral ataxia, ipsilateral impaired taste, ipsilateral facial pain and paresthesia, decreased ipsilateral blink reflex, contralateral hypoalgesia and thermoanaesthesia in the trunk and limbs; and ipsilateral facial hypoalgesia and thermoanaesthesia. Neuroanatomical knowledge is essential to its comprehension, study and diagnosis, because the classic neurological manifestations are easy to explain and understand if function and localization of affected anatomical structures are known as if the posterior cerebral circulation is.
延髓背外侧综合征，又称外侧延髓综合征，是小脑后下动脉供血区梗死的临床表现。其体征和症状包括眩晕、眼球震颤、复视、同侧霍纳综合征、面部发红及皮肤干燥、发音困难、吞咽困难、构音障碍、同侧咽反射消失、同侧共济失调、同侧味觉障碍、同侧面部疼痛和感觉异常、同侧眨眼反射减弱、对侧躯干和肢体痛觉减退及温度觉缺失；以及同侧面部痛觉减退和温度觉缺失。神经解剖学知识对理解、研究和诊断该病至关重要，因为如果了解受累解剖结构的功能和定位，就像了解后循环一样，经典的神经学表现就很容易解释和理解。
