Pediatric vertebral and spinal epidural tumors: a retrospective review of twelve cases.

Objective: Pediatric vertebral tumors are rare, and most of the reported series have limited numbers of cases. Diagnosis of these tumors is difficult because of the patients' age and the rarity of the lesions. We aimed to report the clinical, radiological and pathological characteristics in a small series of pediatric vertebral and spinal epidural tumors and to discuss diagnostic and treatment difficulties.

Materials And Methods: Twelve consecutive pediatric cases with vertebral or spinal epidural tumors were reviewed retrospectively.

Results: The mean age was 12.6 years, and male and female patients were equal in number. The most common symptom was pain. There were some neurological or local findings in all patients, and there were some positive results on plain radiographs in all cases except 2. The tumors were removed totally in 9 cases. There were histologically malignant lesions in 3 and benign lesions in 9 cases. Three patients with malignant tumors were treated by radiotherapy and 2 by chemotherapy. One patient with thoracic hemangioma was also treated by embolization after surgery. One case with cervical Dabska's tumor died due to air embolization. The other patients were followed for 48.3 months. The preoperative neurological deficits were resolved completely in all patients except the one with only biopsy performed at the last follow-up. There were no new spinal deformities on follow-up.

Conclusion: Children with vertebral tumors and spinal epidural tumors usually present with pain and neurological deficits or local findings, and there are some indications on plain radiographs. Therefore, a careful physical examination and detailed evaluation of radiographs may minimize the rate of misdiagnosis and underestimation. Most of these tumors are benign, therefore, their outcome is good, and cure may be possible for many of the cases.
