Management of anteriorly located C1-C2 neurofibromata

Abstract

The authors discuss their recent experience with anteriorly located C1-C2 neurofibromata in five patients with cervical myelopathy and magnetic resonance scans consistent with intradural extramedullary masses in this region. Surgery was performed using a posterolateral approach with microscopic intradural exploration. Gross total intradural tumor removal was achieved in all cases. Improvement in cervical myelopathy occurred in all patients. This report concludes that C1-C2 neurofibromata located anterior to the spinal cord can be totally and safely removed using a posterolateral approach. Improvement in neurologic dysfunction accompanies posterior decompression and gross total intradural tumor removal.

Spinal Meningiomas: A Review

“…Intradural extramedullary spinal cord tumors account for approximately two-thirds of all spinal cord tumors in adults [6]. Meningiomas, neurofibromas, and schwannomas are the most common type of tumor in this type of location [7,8]. Meningiomas represent about 40% of these tumors [6].…”

Microsurgical management of dumbbell C1 and C2 schwannomas via the far lateral approach

“…5,8,9,11 Moreover, C1 and C2 schwannomas are frequently huge and dumbbell-shaped; 2,4-9,12,13 therefore, managing these lesions can be particularly challenging and the surgical planning for them is usually complicated. 3,9,10,[12][13][14][15][16] We report 18 dumbbell C1 and C2 schwannomas resected by the far lateral approach and review relevant studies in the literature.…”

Successful Surgical Excision of Juvenile-Type Spinal Arteriovenous Malformation in Two Stages Following Partial Embolization

“…There have been several surgical reports that describe the anterior approach via corpectomy to treat ossification of the posterior longitudinal ligament, intramedullary tumors, and vascular malformations [23 ± 26]. Although the intraoperative exposure and working space within the dura achieved when performing a corpectomy are limited and dural closure is not easy, such a procedure provides the most direct access to some lesions and has been performed safely in several reports [6,21,25,27,28]. However, there is the risk of cerebrospinal fluid (CSF) leakage, because dural closure is often difficult.…”
