Overview
Some patients with oligodendroglioma may have elevated protein and cell count with normal glucose and lactate on CSF analysis, which is usually suggestive of hydrocephalus.
Laboratory Findings
Lumbar Puncture
- Some patients with oligodendroglioma may have elevated protein and cell count with normal glucose and lactate on CSF analysis, which is usually suggestive of hydrocephalus[1][2]
Immunohistochemical staining
- Oligodendrogliomas stain positive for:[3][4][5]
- IDH1-R132H (majority of cases)[6]
- ATRX
- GFAP (positive in intermingled reactive astrocytes and minigemistocytes)
- SOX10
- MAP2
- S-100
- EMA
- Ki-67
- NSE
- Synaptophysin
- OLIG1
- OLIG2
- Oligodendrogliomas stain negative for:
- p53 (rare weakly positive cells can be seen)
- Keratins (although cocktails may show cross reactivity)
