Spinal Ganglioneuroma.

An otherwise healthy 57-year-old man presented with intermittent low back pain and was incidentally found to have a left-sided paraspinal mass invading the spinal canal and causing spinal cord compression. He underwent a T11-12 hemilaminectomy, facetectomy, and instrumented fusion for a gross total resection with a good clinical outcome. Pathology revealed the lesion to be a ganglioneuroma. Ganglioneuroma is a rare and interesting pathology. These tumors are benign peripheral neuroblastic tumors derived from the neural crest and found along the entire neuroaxis. Tumors come to clinical attention if they cause symptomatic compression of neural structures or are found incidentally on imaging. Additionally, as these tumors share a common lineage with pheochromocytomas, systemic symptoms can be observed resulting from secretion of vasoactive peptides. The pathologic diagnosis of ganglioneuroma is predominantly based on morphology.
