B7.023 Spinal Cord CBCL

Question 1

brief description of neurogenic shock

Answer 1

trauma and spinal shock cause a sudden loss of background sympathetic stimulation to blood vessels
can be seen in high spinal cord injuries (down to T6)

Question 2

cervical cord syndrome

Answer 2

affects anterior horn cells and ALS tract at level of lesion

can grow to impinge upon lateral corticospinal tracts and cause UMN damage to body parts below the lesion

Question 3

what is a etiology of post traumatic cervical cord syndrome

Answer 3

syrinx
inflammatory inclusion in the central cord
can grow and expand

Question 4

what etiology would cause a hemi cord syndrome to progress to a full cord syndrome

Answer 4

extra-axial tumor
initially compresses one side, but eventually grows to a critical point where more deficits are seen very quickly as the cord can no longer compensate

Question 5

extradural lesions

Answer 5

chondromas
sarcomas
(metastatic tumors)

Question 6

intradural, extramedullary lesions

Answer 6

meningiomas

neurofibromas

Question 7

intramedullary lesions

Answer 7

gliomas

ependymomas

Question 8

lesion that could lead to myeloradiculopathy

Answer 8

unilateral external compression

compresses nerve root and corticospinal tract
