What Researchers Did
Researchers reported a case of spontaneous subarachnoidal pneumocephalus in an occupational diver after a 20-meter dive.
What They Found
An occupational diver experienced sudden headache, dizziness, and disorientation at 17 meters during a 20-meter dive. CT scans revealed air in the subarachnoidal space and a bony defect in the sphenoid sinus. One year later, he still suffered from central nervous symptoms and post-traumatic stress disorder, preventing him from working or diving.
Canadian Relevance

Study Limitations
As a single case report, the findings of this study cannot be generalized to a larger population of divers.
