what runs through the wall of the cavernous sinus
CN3,4,V1,V2
NOT CN2 or V3
which CN is most likely to be affected first by a cavernous ICA aneurysm?
- it’s the nearest one to it
this is the sella turcica
what bone and what are the four little corners called and what attaches to thwm
sphenoid
clinoid processes
dura
tghis is the back of the sphenoid. what is this part called and where does it slope towards
Clivus
towards foramen magnum
bitemporal hemianopia suggests…because…
pituitary gland tumour… optic chiasm is directily superior to the pituitary gland
