Anatomy cavernous sinus thrombosis

A 16-year-old girl with much facial acne has continued to pick at and squeeze her ‘pimples.’ One day facial bacteria from one of her open sores enters her facial veins and travels to the right cavernous sinus of her brain, causing a cavernous sinus thrombosis. Which two structures in the cavernous sinus of the brain will be most affected?

A Cranial nerves II and III
B Cranial nerves V1 and V2
C Sphenoid bone and internal carotid artery
D Cranial nerve VI and internal carotid artery
E Cranial nerves IX and IV

You should modify your mnemonic. The internal carotid artery like the other four run in the lateral wall. Only the abducent nerve run freely in the middle and that's it's first affected by cavernous sinus thrombosis.

By the way it's called mnemonic not pneumonic

Moreover, the clinicopathologic significance entails that we only think of the abducent nerve as hanging freely in the cavernous space and therefore you mnemonic may get people confused over the early affection of the Abducent nerve.
