Overview
Acoustic neuroma may be classified into three subtypes based MRI, and into four subtypes based on microscopic histopathology.
Calssification
Based on the MRI scan, acoustic neuromas can be classified into three subtypes:
- Entirely intracanalicular: The entire tumor is completely within the bony canal.
- Intracranial extension without brain stem distortion.
- Intracranial extension with brain stem distortion.
Based on microscopic histopathology, acoustic neuroma can be classified into four subtypes:Closing </ref> missing for <ref> tag
