Minimally Invasive Intradural Tumor Resection.

Abstract

In conjunction with neurofibromas, schwannomas are the second most commonly occurring intradural extramedullary tumor. They are a benign encapsulated nerve sheath tumor that are typically slow growing. They occur equally as frequently in the cervical and lumbar spine. If symptomatic, surgical resection may be warranted. In this surgical technique video, we present a case of a 70-year-old woman who presented with worsening symptoms consistent with cauda equina syndrome secondary to intradural masses at the L1-2 level. A minimally invasive resection of the intradural lesions was performed without any complication. Final pathology of the resected masses revealed schwannoma.
