A 56-year-old woman presented with right leg paresthesia for the previous year. Magnetic resonance imaging showed an intradural extramedullary tumor in the left anterolateral cervical spine. An operation was performed through the posterior approach. Intraoperative findings showed that the tumor was generated from the anterior nerve root. Total resection was performed. The histopathological diagnosis was schwannoma (World Health Organization grade 1). Immediately after the operation, the right leg paresthesia disappeared completely. Slight motor weakness of the left upper extremity appeared postoperatively but was restored two weeks later.
Key words: Contralateral paresthesia, schwannoma, anterior nerve root.
