Extensive intramedullary schwannoma of the sub-axial cervical spine – A case report
Publication date: March 2020Source: Interdisciplinary Neurosurgery, Volume 19Author(s): Adrian Kelly, Patrick Lekgwara, Aftab YounusAbstractSpinal schwannomas originate from Schwann cells and as a group represent 30% of spinal cord tumors. These lesions are commonly intra-dural extramedullary in location and in fact purely intramedullary schwannomas of the spinal cord represent only 1.1% of spinal schwannomas. Almost all of these occur in patients with Neurofibromatosis. Approximately 50 cases of intramedullary schwannomas not related to neurofibromatosis have been described to date.This case report gives an account of a young male patient with no family history nor clinical signs of Neurofibromatosis whom presented to out institution with an extensive schwannoma of his sub-axial cervical spinal cord extending from C4-T2. Neurological examination of his upper limbs on manual muscle testing revealed normal shoulder and elbow power 5/5, weakness of wrist dorsiflexion 3/5 and wasting of his intrinsic hand muscles bilaterally also with power 3/5. His lower limb examination revealed an incomplete T4 sensory level with preserved sensation and on manual muscle testing no motor function 0/5 was present. Under neurophysiological monitoring he was taken to theatre where the intra-operative finding of the schwannoma being subpial and intramedullary was confirmed. A gross total resection was achieved and post operatively his upper limb function showed no deterioration and his lower limb ...
Conclusion: In this first MSM analysis we delineated a refined description of PLGG disease course over time, identifying three levels of progressiveness. Growth behavior in the first two years predicted future progressiveness and death.
Conclusions: Rehabilitation of hearing with CI provides a favorable long-term outcome in patients with NF2-related IVS which could be altered by the occurrence of other intracanalicular and/or CPA NF2-related tumors.
Conclusion: Tacrolimus, an immunosuppressant used to prevent rejection in organ transplant, could lead to VS volume shrinkage and hearing improvement. Tacrolimus could be an interesting new therapeutic weapon, especially for VS in Neurofibromatosis type 2.
Conclusions: Our goals for NF-1 scoliosis are to obtain deformity correction, to achieve stable instrumentation by using longer fusion levels and to attain a solid fusion mass that can tolerate continual erosion during the long-term follow-up. We achieve this by using a circumferential approach for EOS associated with NF-1. Level of Evidence: Level IV—case series.
This article provides an overview of CALMs, followed by a summary of several conditions associated with CALMs ranging from the most common (neurofibromatosis type 1) to rare, ring chromosome syndromes.
We present the case of a woman with a de novo mutation in the NF2 gene who later developed MS. In addition, we found a significantly higher count of T cells in a laryngeal schwannoma of this patient as compared to a schwannoma removed from a NF2 patient without MS. This finding correlated with a higher growth rate in the case of NF+MS.

CONCLUSIONS: Fluorescein was demonstrated to be a feasible, safe, and helpful intraoperative adjunct to better identify and distinguish PNSTs from intact functional nerves, with a possible impact on tumor resection, particularly in diffuse neurofibromas.

Neurofibromatosis type 1 is an inherited condition with variable phenotypic expression and a high medical and social burden.
Neurofibromatosis-1 (NF-1) has a known increased risk of malignancy with rhabdomyosarcoma occurring in up to 6% of patients. Here we report on an 8-year-old male with a history of NF-1and previously treated stage 3, group III bladder/prostate embryonal rhabdomyosarcoma (diagnosed at 18 months old) who presented with penile swelling concerning for priapism. Imaging and subsequent biopsy confirmed embryonal rhabdomyosarcoma of the penile corporal bodies. Penile rhabdomyosarcoma is exceedingly rare, with less than 15 case reports in the literature.
