CNS tumours

CNS tumours

- 60% = Glioma and metastatic disease

• 20% = Meningioma
• 10% = Pituitary lesions

In paediatric practice medulloblastomas (neuroectodermal tumours) were the commonest lesions, astrocytomas now account for the majority.
Tumours arising in right temporal and frontal lobe may reach considerable size before becoming symptomatic. Whereas tumours in the speech and visual areas will typically produce early symptoms.

Diagnosis
MRI Scanning provides the best resolution.

Treatment
Usually surgery, even if tumour cannot be completely resected conditions such as rising ICP can be addressed with tumour debulking and survival and quality of life prolonged.
Curative surgery can usually be undertaken with lesions such as meningiomas. Gliomas have a marked propensity to invade normal brain and resection of these lesions is nearly always incomplete.
