...-grade astrocytomas compared to adults, with favorable outcomes after resection [ 25, 26 ]. On the other hand, intramedullary ependymomas present as well-circumscribed lesions and are often associated with syrinxes that improve identification of resection margins. The tumor can remain stable without...
