| Summary: | BACKGROUND: Primary spinal cord intramedullary tumors are rare and present with insidious symptoms. Previous treatment protocols emphasized biopsy and radiation/chemotherapy but more aggressive protocols have emerged. OBJECTIVE: To report our experience. METHOD: Forty-eight patients were diagnosed with primary intramedullary tumors. The cervical cord was involved in 27% and thoracic in 42% of patients. Complete microsurgical removal was attempted whenever possible without added neurological morbidity. RESULTS: Complete resection was obtained in 33 (71%) patients. Neurological function remained stable or improved in 32 patients (66.7%). Ependymoma was the most frequent tumor (66.7%). CONCLUSION: Neurological outcome is superior in patients with subtle findings; aggressive microsurgical resection should be pursued with acceptable neurological outcomes.<br>INTRODUÇÃO: Tumores intramedulares primários são raros e apresentam-se com sintomas insidiosos. Protocolos de tratamento anteriores enfatizavam biópsia e radio/quimioterapia, mas protocolos mais agres-sivos têm surgido. OBJETIVO: Relatar nossa experiência. MÉTODO: Tumores intramedulares foram diagnosticados em 48 pacientes. O segmento cervical estava envolvido em 27% e torácico em 42% dos pacientes. Remoção completa foi tentada quando possível sem aumento da morbidade neurológica. RESULTADOS: Ressecção total foi obtida em 33 (71%) pacientes. Função neurológica: permaneceu inalterada/melhorou em 32 (66,7%) pacientes. O tumor mais freqüente foi ependimoma (66,7%). CONCLUSÃO: O prognóstico é melhor em pacientes oligossintomáticos; ressecção microcirúrgica agressiva deve ser tentada sempre, com resultados clínicos aceitáveis. |
