Please help me decipher the MRI report in layman’s terms

[Autumnbird]

Hello I am due to have a translab approach surgery in Nov.
My hearing on left side is severely impaired. The doc has explained to me that my AN is medium sized and needs to come out. If you could share any inputs in layman’s terms and explain to me what the following MRI findings mean, I’d be grateful. I understand that I am not seeking medical counseling here just a more general perspective from fellow patients! More specifically, do you agree that it is “medium sized” as my doc explained.

MRI finding: “there is a 1.5 cm enhancing left cerebellopontine angle mass with extension of enhancement along the proximal 7th and 8th nerve complex measuring approximately 8 mm”.

Is the measurement of the tumor 1.5 cm or 8mm? Would your doctor describe this as small or medium?

I'm not a doctor, but with that being said, this sounds like a pretty classic medium sized tumor. Mine was 1.2 and I was told that it's on the large side of small.  For you, the 1.5 is the overall size, but the "extension" is usually the tumor emerging out of the auditory canal, which is probably why they want to do translate rather than middle fossa.

Greece Lover, Thanks so much for clarifying!
