Prolonged cycling triggers pneumomediastinum in rare case
The 23-year-old patient had a prior history of clinically stable asthma but denied other associative factors, doctors report.
US doctors have detected a “unique” link between intense exercise and pneumomediastinum, after a young cyclist presented with chest tightness and dyspnoea without any typical triggers or causes.
The 23-year-old’s summer routine included cycling for two hours every day, but on the day in question he continued for three and half hours before needing to stop due to feeling unwell.
