Giant extradural spinal schwannoma in a non-neurofibromatosis child-case report and review of literature.

ABSTRACT

Spinal schwannoma is a rare occurrence in non-neurofibromatosis (NF) pediatric patients, especially in the extradural space extending beyond two vertebral levels. Within this age group, the common extradural tumors are either soft tissue sarcomas or metastasis, often with vertebral bony involvement. Spinal schwannomas are usually benign, slowly progressive, well-defined, intradural extramedullary lesion showing homogenous contrast enhancement on imaging. Though its clinical presentation may be with marked neurological involvement, timely surgical excision usually leads to a quick recovery of the deficits in the young age.This case report describes a giant, spinal, benign schwannoma in a 6-year-old boy which was extradural in location. The lesion was resected completely, and since then, he has been asymptomatic, tumor-free for over 3 years.
