(46) Spinal Cord Syndromes

Question 1

lesions to the spinothalamic tract result in

Answer 1

+ babisnki; hyperflexia; weakness (=difficulty walking)

Question 2

key presenting sensory features of brown sequard

Answer 2

contralateral pain and temp insensitive
ipsilateral loss of proprioception and vibration
ipsilateral weakness and + Babinski/hyperreflexive below lesion and LMN flaccid paralysis AT level of lesion

Question 3

drug given as protocol to pts with spinal cord injury

Answer 3

methylpredisolone

Question 4

dumbell shaped mass on spine seen on MRI

Answer 4

nerve sheath tumor (schwannoma/neurofibroma)

Question 5

which spinal cord tract is usually first affected in a central cord lesion? how would this manifest?

Answer 5

spinothalamic = loss pain and temp across trunk (later stages is when the loss moves down the legs)
= cape

**it is the most central tract = EARLY sign

Question 6

presentation of ASA syndrome

Answer 6

intact DC-ML = maintiain proprioception/vib sense

loss of pain and temp bilaterally and loss of motor bilaterally

Question 7

flaccid paralysis + complete sensory loss + urinary retention =

Answer 7

cord shock/acute spinal injury

Question 8

tracts affected by B12 def and the presentation

Answer 8

DC-ML and CST
bilateral loss of vib and position
bilateral spastic paralysis
BEEFY tongue

Question 9

HAM/TSP pts are infected with ___ which causes ___ and presented as ____

Answer 9

HTLV-1 causes demeylination (DC > PC)and axonal degeneration presentiang as loss of vib and postion sense > spastic paralysis

Question 10

who gets vacuolar myelopathy and how does it presents

Answer 10

late stage AIDS

demeylination of DC and lateral columns –> spastic paralysis, and loss of vib/position sense (~B12 def)

Question 11

neuro-complication of the shyph

Answer 11

tabes dorsalis (DC dysfunction)
