Large Cystic Intradural Schwannoma Extending from L2 to S4 Spinal Segments: A Case Report

Schwannoma originates from the sheath of spinal cord roots neurilemma or Schwann cells (so it is mainly called neurilemmoma or Schwannoma) and makes one third of primary spinal cord tumours [1-6]. The tumour localization is in various parts of spinal cord, but prevailsin cervical and thoracic, rare in lumbar and sacral regions [1-7]. It can grow exophytic above and below the dura of spinal cord (extremely rare intramedullary) or involve the spinal root and interfere its fibres. According to histological structure schwannoma is a benign tumor, but growing in the narrow spinal canal may cause canal compromise resulting in cord compression and its squeal. Degenerative changes like haemorrhage, calcification, and fibrosis are commonly seen in schwannom as, but cystic changes are rare.
