First reported case of air leaking into the spine from cannabis hyperemesis vomiting
A young patient with cannabinoid hyperemesis syndrome developed both pneumomediastinum (air in the chest cavity) and pneumorrhachis (air around the spinal cord), the first reported case combining CHS with spinal air leak.
Quick Facts
What This Study Found
This is the third reported case of CHS with associated pneumomediastinum and the first documented case of pneumorrhachis (air in the spinal canal) linked to CHS. The complications resulted from forceful, repeated vomiting associated with the syndrome.
Key Numbers
Third case of CHS with pneumomediastinum in the literature. First case of CHS with pneumorrhachis ever reported.
How They Did This
Single case report with literature review.
Why This Research Matters
CHS is becoming more common as cannabis use increases. Severe vomiting can cause rare but serious mechanical complications, and clinicians need to consider these possibilities when evaluating CHS patients with unusual symptoms.
The Bigger Picture
As CHS diagnoses increase with rising cannabis use, rare complications that were once one-off curiosities may become clinically significant patterns worth screening for.
What This Study Doesn't Tell Us
Single case report. Cannot establish frequency or risk factors for these complications in CHS. No long-term follow-up reported.
Questions This Raises
- ?How often do CHS patients develop pneumomediastinum or other mechanical complications from severe vomiting?
- ?Should imaging be standard for CHS patients with chest or back pain?

What do these levels mean? →Frequently Asked Questions
Can cannabinoid hyperemesis cause serious complications?
Yes. This case report documents air leaking into the chest cavity and spinal canal from forceful vomiting caused by CHS, a rare but potentially dangerous mechanical complication.
What is pneumorrhachis?
Pneumorrhachis is the presence of air within the spinal canal. In this case, it resulted from severe, repeated vomiting associated with cannabinoid hyperemesis syndrome.
