Resumo

Os tumores da bainha nervosa são os segundos tumores mais comuns da coluna vertebral. No entanto, os schwannomas lombares puramente extradurais são extremamente raros. Geralmente, estes casos são abordados posteriormente por meio de uma incisão na linha média com laminectomia com ou sem facetectomia, dependendo da localização do tumor. Apresentamos um caso de uma paciente de 40 anos com schwannoma lombar puramente extradural que foi tratado com a abordagem de Wiltse, focando principalmente nas principais dicas e truques dessa abordagem.

Abstract

Nerve sheath tumors are the second most common spinal tumors. However, purely extradural lumbar schwannomas are extremely rare. Generally, these cases are approached posteriorly through a midline incision with laminectomy with or without facetectomy, depending on the location of the tumor. We present a case of a 40-year-old patient with purely extradural lumbar schwannoma who was treated via the Wiltse approach, focusing mainly on the main tips and tricks of this approach.
