left side. What is the most definitive inv?
a. CT scan of internal auditory meatus
b. Nuclear imagine of the brain
c. MRI of internal auditory meatus
d. MRI brain
Answer: D
Vertigo, SNHL & cranial nerve involvement (in this case corneal reflex) = Acoustic neuroma.
It starts in the internal audioty canal but expands into the CPA, therefore we would like to see more than just the internal audioty meatus, so MRI brain is a more appropriate choice. If the only option given was MRI i.a.m, then it would be correct to choose it.
