Surgical technique for executing an <i>en bloc</i> resection of a multilevel cervical intramedullary ependymoma: A 2D operative video.

ABSTRACT:

Background

We present the case of a 39-year-old female with progressive loss of dexterity, gait imbalance, sensory deficits, and neuropathic pain in her bilateral upper and lower extremities. She presented with hyperreflexia, bilateral Hoffmann's sign, and clonus. Magnetic resonance imaging (MRI) demonstrated a mid-cervical intramedullary mass with polar cysts, distal syringomyelia, and brainstem edema. We therefore performed a C2-C7 laminectomy with posterior instrumentation for tumor resection.

Case description

We showcase a high-definition operative video with a step-by-step demonstration of this procedure. Key steps are detailed, such as the use of dorsal column mapping to confirm the electrophysiological midline. Crucial surgical maneuvers such as techniques of peeling
