Astrocytomas are the most common intramedullary spinal cord tumor in pediatric and adolescent patients and the incidence decreases with age. There are very few cases of spinal pilocytic astrocytomas (World Health Organization grade 1) reported after the fourth decade 1).

see Intramedullary astrocytoma.


Intramedullary spinal cord tumors (IMSCT) are rare lesions and constitute only 4-10% of all primary central nervous system tumors 2) 3).

IMSCTs are less common in adults than in children and constitute 20% and 35%, respectively of all intraspinal tumors 4) 5) 6) 7).

The most commonly occurring intramedullary neoplasm is spinal cord ependymoma followed by spinal cord astrocytoma and other lesions 8) 9) 10) 11).
