[A] Glioblastoma
[B] Medulloblastoma
[C] Oligodendroglioma
[D] Astrocytomas
Oligodendroglioma most commonly seen in
[A] Frontal lobe
[B] Temporal lobe

[D] Cerebellum
Oligodendroglioma
“chicken wire” pattern.
Oligodendroglioma – has a network of thin blood vessels that appear as a “chicken wire” pattern.
Oligodendroglioma most commonly seen in – Frontal Lobe
Oligodendroglioma
Most common site of Oligodendroglioma
- Cerebral hemisphere
- White matter
- 80 to 90% supratentorial
- Most commonly in the frontal lobes
Most common mutation in oligodendroglioma
Most common mutation in oligodendroglioma is the isocitrate dehydrogenase 1 (IDH1) R132H gene mutation, which is found in more than 90% of grade II oligodendrogliomas.
*Most common tumor mutation in general [ all cancer] –*
TP53 gene mutation – which is a tumor suppressor gene that controls cell growth and division
