LMS, lateral medullary syndrome; PICA, posterior inferior cerebellar artery Introduction . Lateral medullary syndrome presents with features of ipsilateral Horner syndrome, ipsilateral ataxia, and contralateral hyperalgesia.

Lateral medullary syndrome or posterior inferior cerebellar artery (PICA) syndrome characterized by dissociated sensory loss Affected structures -- resultant deficits include: 1. vestibular nuclei Lesions result in nystagmus, nausea, vomiting, and vertigo. reduced salivation. Horner syndrome. Impairment of cerebral autoregulation occurs in the infarcted area of the brain. Salient features History Severe nausea, vomiting, nystagmus (involvement of the lower vestibular nuclei) Limb ataxia (involvement of the inferior cerebellar peduncle) Intractable hiccups, dysphagia (ninth and tenth cranial nerve involvement). loss of pain and temperature sensation on the ipsilateral (same) side of the face. It contains numerous cranial nerve nuclei and is traversed by multiple tracts between the brain and spinal cord. Capillaries and Sinusoids; Cardiovascular System - Structural Components; Components of Vascular System and Types of Circulation Now, let . And so when we have diplopia, it doesn't have to be from cranial nerves 4, 5, or 6 which live rostrally in the midbrain and the pons. These cranial nerves, as well as the descending sympathetic fibers (patient had a right-sided Horner's sign), are also found in the dorsolateral aspect of the right side of the medulla (Figure 2). 5 Second-order Talk to our Chatbot to narrow down your search.
