Abstract

Background: Intramedullary (IM) schwannomas are rare entities representing 0.3%-1% of intramedullary tumors and 1.1% of spinal schwannomas. Beside many theories proposed, their rare occurrence might be related to the absence of Schwann cells in the spinal cord. Pediatric IM schwannomas are uncommon, and in the absence of neurofibromatosis they are extremely rare. To date, few cases have been reported in the literature.

Case description: We describe the case of an 8-year-old female affected by a progressive paraparesis. Neuroradiologic investigations showed an oval-shaped mass at the level of T10-T11. The patient underwent surgery, performed under neurophysiologic monitoring. The patient was operated on with complete removal of the lesion. The postoperative course was uneventful.

Conclusions: The clinical, neuroradiologic, and intraoperative findings are presented, along with a review of the literature. Despite the number of lesions potentially compressing the spinal cord, IM schwannoma is rare but should be taken into account in the differential diagnosis.

Keywords: Intramedullary tumors; NF syndrome; Pediatric tumors; Schwannomas; Spine surgery.
