[Cerebral embolism during commercial flight: case report].

Area of Science:

• Medicine
• Pulmonology
• Neurology

Background:

• A 25-year-old male with a history of marijuana and tobacco use experienced an in-flight medical emergency.
• Symptoms included dyspnea, loss of consciousness, and seizures during commercial air travel.

Observation:

• Upon arrival, the patient presented with hypotension and absent pulmonary murmur, remaining unconscious.
• Thoracic tomography revealed lung bullae, and cranial tomography showed pneumocephalus.

Findings:

• The patient was diagnosed with cerebral gas embolism.
• Hypoxemia, seizures, and loss of consciousness during flight are uncommon in young individuals.

Implications:

• Reduced cabin pressure during aircraft ascent may act as a trigger for cerebral gas embolism in individuals with underlying lung conditions like bullae.
• This case highlights a rare but serious complication of air travel in susceptible individuals.
