We aimed to present the clinical and radiological outcomes of 22 cases of cervical spinal meningiomas.
We retrospectively reviewed 22 patients who were diagnosed with cervical meningioma histologically from May 2003 to May 2017. Their pre- and postoperative clinical features were evaluated by the Japanese Orthopaedic Association (JOA) scale and Neck Disability Index (NDI).
There were 6 male and 16 female patients. The mean age was 60 years (20 to 73 years). The most common preoperative symptom was paresthesia in 15 patients. The craniocaudal tumor extension of less than 3 levels was found in 18 patients. More than 50% of spinal canal compression was observed in 16 patients. Most common location of the dural attachment of the tumor was ventrolateral (54.5%), followed by dorsolateral (18.2%), lateral (13.6%), ventral (9.1%) and dorsal (4.5%) order. Extradural tumor extension was observed in 5 patients. Simpson grade II resection was the most common, with 16 patients. The mean JOA scales were significantly improved from 13.8 ± 2.6 to 15.9 ± 1.0 at postoperative one year (p = 0.0004). The mean NDI showed the same results (from 14.6 ± 8.2 to 8.4 ± 6.6, p = 0.0005). One patient with Simpson grade IV resection received adjuvant radiotherapy. Two patients had a recurrence of the tumor, one with Simpson grade II resection and the other with Simpson grade III resection.
The surgery is the recommended treatment in cases of cervical spinal meningiomas because of its excellent functional improvement and low recurrence rates.
