Student died after rare brain abscess misdiagnosed as sinusitis

A 21-year-old university student, Cian Everett, tragically died in January 2025 after his rare brain abscess, which led to meningitis, was misdiagnosed as sinusitis. His parents are now campaigning for healthcare improvements to prevent future deaths. Cian experienced a sudden, severe headache, often termed a 'thunderclap headache.' Despite contacting NHS 111 three times and seeking care at Lymington Urgent Treatment Centre, his condition was not accurately diagnosed. An inquest revealed that South Central Ambulance Service made an error in referring Cian to the Lymington centre, which lacked the necessary facilities for his symptoms. The centre also missed opportunities to take his care more seriously, as notes detailing his condition were not fully reviewed by clinicians. The coroner issued a report to PHL Group, which manages the Lymington Urgent Treatment Centre, highlighting concerns. PHL Group stated patient safety is a priority and they are reviewing the findings. Cian's parents emphasize the importance of patients providing comprehensive information to healthcare providers. They also point to Jess's Rule, a law enacted in September 2025, which mandates reviews after multiple primary care interactions with escalating symptoms, suggesting it could have aided Cian's case. Following their son's death, the Everett family established the Cian Everett Young Person's Development Foundation to support young people.
