Intraspinal pilocytic astrocytomas: An overview and 2-D illustrative resection technique video.

ABSTRACT:

Background

Spinal cord pilocytic astrocytomas (PAs) are rare and typically occur in pediatric patients. While PAs are often well-circumscribed and amenable to gross total resection, they sometimes harbor infiltrative components that can invade normal cord parenchyma.

Methods

Here, we present a 59-year-old female with a progressive right-sided hemi-sensory loss, right-sided hemiparesis, and gait imbalance. The preoperative T2 magnetic resonance imaging revealed a large loculated cystic tumor that focally compressed the dorsal medulla, while the contrast study revealed a 1.3 cm homogenously enhancing expansile intramedullary mass centered at the C1 level.

Results

The patient underwent a C1-2 laminectomy followed by gross total intramedullary tumor resection utilizing in
