Multiple extraspinal recurrences of ependymoma 13 years after spinal cordectomy: case report.

Ependymomas of the spinal cord remain confined to the CNS and vary in presentation, depending on WHO grade. Higher-grade lesions usually cannot be surgically removed due to their infiltrative growth pattern. Spinal cordectomy has been proposed as a rescue treatment to improve survival in patients with high-grade as well as recurrent lesions.

De Novo Spinal Dural Arteriovenous Fistula in a Patient with a Lipomyelomeningocele: Case Report.

Background: Spinal dural arteriovenous fistula (AVF), the most common type of spinal vascular malformation, tends to manifest as progressive myelopathy over several years. Spinal dural AVFs are considered an acquired lesion and, in contrast to spinal arteriovenous malformations, are not often associated with other anomalies. The presence of a spinal dural AVF in the setting of a lipomyelomeningocele and tethered cord is extremely rare.
