Reveal Findings

MR – Sagittal T2 and post-gadolinium T1 images of the spine show a long segment of cord expansion from the pontomedullary junction to the mid-thoracic cord related to patchy enhancing neoplasm and marked vasogenic edema.

Reveal Discussion

Ganglioglioma is a rare CNS tumor (~1% of CNS tumors). Gangliogliomas are composed of a mixture of neoplastic neuronal or ganglion and glial (usually astrocytic) cells; classification is based on the degree of differentiation of the neuronal or ganglion cells. Gangliogliomas are slow growing relatively benign tumors but have a recurrence rate of nearly 50%. Of totally resected spinal cord tumors, low-grade astrocytoma is most common followed by ganglioglioma and then ependymoma and high-grade astrocytoma. Gangliogliomas are associated with long segment or holocord involvement, reactive and tumoral cysts, scoliosis and bony remodeling.
