Abstract

The optimal approach to intradural tumors remains controversial. All the techniques may have advantages and disadvantages when applied alone. Combining two different techniques in a tailored way could be safer and more effective for individual patients. A 53-year-old female patient was admitted to our clinic with complaints of back pain, walking difficulty, and numbness in her left foot that had been going on for one and a half years. Gadolinium-enhanced: -enhanced T1-weighted magnetic resonance imaging of the thoracic spine revealed a contrast-enhanced intradural extramedullary mass lesion, ∼40 × 15 mm in size, with a cystic component; the lesion extended from the level of the lower end plate of the T7 vertebral body to the mid-level of the T9 vertebral body. The patient was operated on using a tailored laminoplasty–hemilaminectomy technique, and gross total resection of the intradural extramedullary large tumor was achieved. Gross total excision of large intradural extramedullary schwannomas can be safely performed using a tailored laminoplasty–hemilaminectomy approach, where unilateral hemilaminectomy can be performed at multiple levels, whereas laminoplasty is limited to a single level.

Resumo

A abordagem ideal para tumores intradurais permanece controversa. Todas as técnicas podem ter vantagens e desvantagens particulares quando aplicadas isoladamente. Combinar duas técnicas diferentes de maneira personalizada pode ser mais seguro e eficaz para pacientes individuais. Uma paciente do sexo feminino, de 53 anos, foi admitida em nossa clínica com queixas de dor nas costas, dificuldade para caminhar e dormência no pé esquerdo, sintomas que duravam um ano e meio. A ressonância magnética da coluna torácica ponderada em T1 com contraste de gadolínio revelou uma lesão intradural extramedular com realce de contraste, aproximadamente 40 × 15 mm de tamanho, com um componente cístico; a lesão se estendia desde o nível da placa terminal inferior do corpo vertebral de T7 até o nível médio do corpo vertebral de T9. A paciente foi operada utilizando uma técnica personalizada de laminoplastia–hemilaminectomia, e foi alcançada a ressecção total macroscópica do grande tumor intradural extramedular. A excisão total macroscópica de grandes schwannomas intradurais extramedulares pode ser realizada com segurança usando uma abordagem de laminoplastia–hemilaminectomia personalizada, onde a hemilaminectomia unilateral pode ser realizada em vários níveis, enquanto a laminoplastia é limitada a um único nível.
