Abstract
A case of resection of a large dumbbell-shaped nerve sheath tumor at L1/L2 via a direct lateral minimally invasive approach is described. The tumor was removed via a lateral, subdiaphragmatic, rib-sparing, retropleural, retroperitoneal approach. The thoracolumbar junction can be challenging via the lateral approach and to the best of our knowledge this is the first report of excision of a paravertebral tumor via this approach. We believe this provided the benefits of direct operative trajectory and exposure, excellent tumor access, and avoided the need for facetectomy and extended spinal instrumentation across the thoracolumbar junction. Complete tumor excision was achieved with preserved motor function and improvement in radicular pain and sensory neurological deficit.
