Resection of a lumbar intradural tumor.

ABSTRACT:

Background

Myxopapillary ependymomas and schwannomas represent the most common tumors of the conus medullaris and cauda equina. Here, we present the surgical resection of a 64-year-old male with a lumbar intradural tumor.

Case description

A 64-year-old male presented with several months of the lower extremity weakness, pain, and bowel/bladder dysfunction. Magnetic resonance imaging demonstrated a large L3-5 intradural lesion, and surgical resection using intraoperative neuromonitoring with somatosensory evoked potentials (SSEPs), motor evoked potentials (MEPs), free-running electromygraphy (EMGs), and direct sphincter monitoring was recommended. After an L2-S1 laminectomy was performed, intraoperative ultrasound was used to confirm the cranial and caudal extent of the tumor.
