Contralateral impairment of pain and temperature sensation

Table 6 Medullary syndromes (p. 73) Medial Medullary Lesions

Cause. Occlusion of the anterior spinal artery or vertebral artery.

Table 6 Medullary syndromes (p. 73) Medial Medullary Lesions

Cause. Occlusion of the anterior spinal artery or vertebral artery.

Structures Affected

Symptoms and Signs

Hypoglossal n. nucleus/fibers

Ipsilateral peripheral (nuclear) hypoglossal paralysis

Pyramidal tract

Contralateral central paralysis sparing the face (flaccid, in isolated pyramidal tract lesions)

Medial lemniscus

Contralateral impairment of touch, position, and vibration sense (pain and temperature sensation intact)

Medial longitudinal fasciculus

Upbeat nystagmus

Lateral Medullary Lesions (Dorsolateral Medullary Syndrome, Wallenberg Syndrome)

Cause. Occlusion of posterior inferior cerebellar artery (PICA) or vertebral artery. Less common causes: tumor, metastases, hemorrhage due to vascular malformations, multiple sclerosis, vertebral artery dissection (after chiropractic maneuvers), trauma, gunshot wounds, cocaine intoxication.

Site of Lesion

Symptoms and Signs

Spinal nucleus of trigeminal nerve

Ipsilateral analgesia/thermanesthesia of the face and absence of corneal reflex with or without facial pain

Cochlear nucleus

Ipsilateral hearing loss

Nucleus ambiguus

Ipsilateral paralysis of the pharynx and larynx (hoarseness, paralysis of the soft palate), dysarthria, and dysphagia. Tongue movement remains intact

Solitary nucleus

Ageusia (impaired sense of taste)

Dorsal nucleus of vagus n.

Tachycardia and dyspnea

Inferior vestibular nucleus

Nystagmus away from the side of the lesion, tendency to fall toward the side of the lesion, nausea and vomiting

Central tegmental tract

Ipsilateral myorhythmia of the soft palate and pharynx

Central sympathetic pathway

Ipsilateral Horner syndrome

Reticular formation


Inferior cerebellar peduncle

Ipsilateral ataxia and intention tremor

Anterior spinocerebellar tract

Ipsilateral hypotonia

Lateral spinothalamic tract

Contralateral loss of pain and temperature sensation with sparing of touch, position, and vibration sense (sensory dissociation)

Involvement of the lower pons produces diplopia. Occipital pain in Wallenberg syndrome is most commonly due to vertebral artery dissection.

Congenital bilateral facial palsy and cranial nerve involvement (bilateral: VI; unilateral: XII, IV, VIII, IX)

Synkinesis (involuntary co-movement of facial muscles, e. g., narrowing of palpebral fissure when the lips are pursed); hemifacial spasm

Faulty regeneration of CN VII after facial palsy. Nerve root compression and segmental demyelination in hemifacial spasm

Pseudobulbar palsy

Multiple bilateral supratentorial or pontine vascular lesions

Myopathic facies

Myopathic disorders (myotonic dystrophy, my-asthenia, facial-scapular-humeral muscular dystrophy)

Gustatory sweating (Frey syndrome) or lacrimation ("crocodile tears")

Faulty regeneration of the auriculotemporal/facial nerve

Progressive facial hemiatrophy


Table 8 Neurological Causes of Dysphagia (p. 102)

Symptoms and Signs Site of Lesion

Delayed swallowing reflex, aspiration (especially of fluids), prolonged oral phase (pseudobulbar palsy, akinesia, dysarthria, dys-phonia, salivation, oromandibular dystonia)

Loss of swallowing reflex, impaired pharyngeal phase, impaired cough reflex (bulbar palsy, dy-sarthria, respiratory disturbances), risk of aspiration

Weakness of muscles of mastication, impaired oral phase, impaired lip closure, nasal drip; impaired pharyngeal phase (dy-sarthria) may occur: depending on which nerve/muscle is affected

Same as above (generalized my-opathy, dysphonia)

Psychogenic pain

Discrepancy between symptoms and organ findings and/or syndrome classification

Mental illness

1 Selected types. 2 Features may overlap. 3 = nociceptor pain. 4 Pain evoked by a normally nonpainful stimulus.
