Lesion Deficit Patterns Flashcards
(15 cards)
Brown Sequard Syndrome
Ipsi UMN below
Ipsi touch body below
Contra pain 1-2 segs below
(Dissociated sensory deficits)
Central Cord Lesion
Bilateral symmetrical pain
Symptoms increase with larger lesion
Can get ipsi LMN UE with ipsi UMN below if the lesion extends rostrocaudally over several segments
Inferior Alternating Hemiplegia (middle medullary syndrome)
Contra UMN body Contra touch body Contra pain face NO loss of pain body Ipsi tongue paralysis Dysarthria
Inferior alternating hemiplegia damaged structures
CST & CN XII
Lateral Medullary Syndrome
Small lesion Ipsi pain face Contra pain body (Alternating hemianalgesia) Horner’s syndrome
Large Lesion Ataxia/nystagmus/vertigo Dysphagia/dysphonia Erratic BP/heart rate/gut pain Loss sensory limb corneal reflex – no blink bilaterally NO UMN/touch loss
Middle alternating Hemiplegia damaged structures
CST & CN VI
Middle alternating Hemiplegia
Contra UMN body
Ipsilateral lateral rectus palsy
Locked-In Syndrome
UMN full body/lower face bilaterally
NO touch or pain loss
Dorsolateral Pontine Lesion (rostral pons)
Contra touch/pain body
Contra Touch/Pain Face
NO motor loss
Superior Alternating Hemiplegia (weber’s syndrome)
Contra UMN body
Ipsi CN III Palsy
NO sensory loss
Superior Alternating Hemiplegia Damaged Structures
CST & CN III
Dorsolateral Midbrain Lesion
Contra touch/pain body
Contra touch/pain face
NO motor loss
Posterior Limb Internal Capsule
Contra touch/pain body
Contra touch/pain face
Contra UMN Body
NO motor loss to the face
Genu/CBT lesion above CN VII motor nucleus
Contra lower face paralysis Contra upper face spared Contra palate paralysis Uvula deviates toward lesion Dysphagia/Dysphonia Tongue deviates away from lesion Dysarthira
