Neuro Anterior Spinal Artery Infarction

Hi there.
I found something in MTB2 that is different from what is described in FA step1.
ASA (anterior spinal artery infarction): the lesion was said to include loss of pain and temperature/ Loss all the function except for posterior column in MTB2.
But in FA, it was said to be different. It should be a lesion involves medial lemniscus. in this case, there should be a loss of proprioception while has no effects on pain or temperature sensation. Am I right?

well if it involves brain stem portion then yes
if it involves lower portion-the spinal cord then everything other than dorsal columns is affected
