Case:
This case of a 14-year-old boy presented with repetitive coughing secondary to a rhinovirus infection. In addition to pneumomediastinum, imaging demonstrated asymptomatic, yet significant holocord pneumorrhachis.
Conclusion:
Ectopic gas within the spinal canal, also referred to as pneumorrhachis or “epidural gas,” may be traumatic, iatrogenic, or less commonly, spontaneous. It is typically an incidental and asymptomatic finding in the setting of pneumomediastinum. Proposed pathophysiology includes air tracking through the intercostal fascial planes posteriorly through the neuroforamina, which offer a theoretical point of entry. Our case clearly demonstrates air along the entirety of the fascial planes confirming the proposed pathophysiology.
