Spontaneous Pneumomediastinum and Cannabinoid Hyperemesis Syndrome: A Case Report and Literature Review
| Journal | Cureus |
| Study Type | Clinical Study |
| Population | Human participants |
This case report adds to the limited literature documenting spontaneous pneumomediastinum as a rare but serious complication of cannabinoid hyperemesis syndrome. With CHS increasingly recognized in clinical practice, understanding its potential complications helps clinicians provide comprehensive care and appropriate monitoring.
This case report describes an 18-year-old male with six months of chronic cannabis use who developed spontaneous pneumomediastinum secondary to forceful vomiting from cannabinoid hyperemesis syndrome. CT imaging revealed mediastinal air without esophageal perforation, and the patient was managed conservatively with bowel rest, antibiotics, and supportive care. This represents only the fifth documented case linking CHS to spontaneous pneumomediastinum in the literature. The case highlights how severe vomiting episodes in CHS can lead to complications beyond the typical gastrointestinal symptoms, requiring clinicians to maintain broader differential considerations.
“While pneumomediastinum remains an exceptionally rare CHS complication, this case reinforces why I counsel patients about the syndrome’s potential severity and emphasize cannabis cessation as the definitive treatment. The rarity shouldn’t diminish our vigilance for complications in patients with severe, prolonged vomiting episodes.”

FAQ
What caused pneumomediastinum in this young cannabis user?
The case report attributes it to forceful vomiting from cannabinoid hyperemesis syndrome (CHS). The patient was an 18-year-old male with six months of chronic cannabis use, and the pneumomediastinum developed spontaneously as a result of his severe vomiting episodes.
How was the pneumomediastinum diagnosed and treated in this case?
CT imaging showed air in the mediastinum and no perforation of the esophagus. With no perforation found, the patient was managed conservatively, using bowel rest, antibiotics and supportive care, according to the case report.
How often has CHS been linked to spontaneous pneumomediastinum?
Rarely. This is only the fifth documented case in the literature linking cannabinoid hyperemesis syndrome to spontaneous pneumomediastinum. The report adds to a limited body of literature describing it as a rare but serious complication of the syndrome.
Can the vomiting in CHS lead to more serious complications?
Yes, according to this case. It highlights that severe vomiting episodes in cannabinoid hyperemesis syndrome can lead to complications beyond the typical gastrointestinal symptoms, as happened here with pneumomediastinum. The report notes this requires clinicians to keep a broader range of possible diagnoses in mind.
