61 year old has had weakness for on the left leg for 6 months. Examination shows increased muscle tone and reflexes in the left lower extremitiy, and an extensor plantar reflex on the left. Where is the lesion?






IS it H or C? And this involves an UMN lesion of the corticospinal right?

I'd say definately H, its a corticospinal tract lesion within the spinal cord which is in the region of H or C. Since there is left sided hemiplegia, that must mean that a lesion has occured in the ipsalateral side of the spinal cord.

H UMN paralysis of the left coricospinal tract

  #4

H is the ans

  #5

H as cst cross at medulla level

  #6

H
