Overview
Surgery is the first-line treatment option for patients with oligodendroglioma. However, oligodendrogliomas cannot be completely resected because of their diffusely infiltrating nature. The aim of surgery is to make a definitive diagnosis, debulk the tumor to relieve elevated intracranial pressure and reduce the tumor mass as a precursor to adjuvant treatment. CSF shunting is usually reserved for patients with hydrocephalus and includes two types of shunts: external ventricular drain-temporary shunt and internal drain-permanent shunt.
Surgery
Surgical Resection
- Surgical resection is the first-line treatment option for patients with oligodendroglioma.[1][2][3]
- Because of their diffusely infiltrating nature, oligodendrogliomas cannot be completely resected.
- The aim of surgery is to:[4]
- Make a definitive diagnosis
- Debulk the tumor to relieve elevated intracranial pressure
- Reduce the tumor mass as a precursor to adjuvant treatment
CSF Shunt
- CSF shunting is performed to relieve the pressure in the brain due to blockade in the flow of cerebrospinal fluid due to oligodendroglioma.[5]
