Sudden collapse of a young female cross country runner

摘要

The case is reported of a young previously healthy female cross country runner who collapsed on completion of a cross country run. The cause of the collapse was non‐cardiogenic pulmonary oedema as a manifestation of hyponatraemic encephalopathy. The concurrent occurrence of non‐cardiogenic pulmonary oedema and encephalopathy due to hyponatraemia is unusual.
