Overview
Other diagnostic studies for oligodendroglioma include biopsy and fluorescent in-situ hybridization (FISH) technique.
Other Diagnostic Studies
Biopsy
Biopsy demonstrates
- Biopsy may be of two types: open or stereotactic.
- Indications for open biopsy include:[1]
- Indications for stereotactic biopsy include:[1]
| Type of biopsy | Indications |

Fluorescent in-situ hybridization (FISH) technique
- FISH demonstrates deletions of chromosome 1p and 19q.[2]
