Abstract Introduction Identifying marathon runners at risk of neurological deterioration at the end of the race within a large cohort complaining of exhaustion dehydration nausea headache dizziness etc. is challenging. Here we report a case of rehydration-related hyponatraemia with ensuing brain herniation. Case presentation We report the death of runner in his 30 s who collapsed in the recovery area following a marathon. Following rehydration he developed a respiratory arrest in the emergency room. He was found to be hyponatraemic 130 mM . A CT brain scan showed severe hydrocephalus and brain stem herniation. Despite emergency insertion of an extraventricular drain he was tested for brainstem death the following morning. Funduscopy demonstrated an acute-on-chronic papilledema CSF spectrophotometry did not reveal any trace of oxyhemoglobin or bilirubin but .
