Intramedullary spinal tumours
Intramedullary spinal tumours are rare, representing 4-10% of all CNS tumours and <10% of all paediatric CNS neoplasms 5. They account for 20% of all intraspinal tumours in adults and 35% of all intraspinal tumours in children 8.
A long duration of symptoms prior to diagnosis is typical.

Leptomeningeal metastases
Leptomeningeal metastases, also known as carcinomatous meningitis and meningeal carcinomatosis, refers to the spread of malignant cells through the CSF space. These cells can originate from primary CNS tumours (e.g. in the form of drop metastases), as well as from distant tumours that have metas...

Intradural extramedullary metastases
Intradural extramedullary metastases are rare and account for approximately 5% of spinal metastases.
Please review leptomeningeal metastases (brain) for a general discussion focused on the brain's subarachnoid space involvement.
Epidemiology
The age at presentation depends on tumour type. Met...
