Spastic hemiparesis on the right
What identifies that a cross-section is medulla vs midbrain vs pons?
@hello I like to pay attention to the Cerebral Aqueduct (diamond/spade shape seen mostly in Midbrain, and transitioning to 4th ventricle in rostral Pons), and then the shape and size of the 4th ventricle as you move down Pons to rostral&middle Medulla, and eventual closing and absence of fluid space at caudal Medulla.
Just for clarification, on the left side, you see where he had the infarction 7 years ago and the tissue is gone.
so is the dysfunction on the contralateral side?
If the decussation is in the pyramids of the medulla, shouldn't it be contralateral hemiparesis if the damage is on the right? It confuses me because of the labeling right and left at the top of the pictures.
that link isnt working @ hayayah....is there any good picture to look at to know where the tracts are on this section?
