Abstract:
Subarachnoid haemorrhage can be a massively debilitating condition with long-term repercussions. The "classic" presentation of sudden-onset severe headache normally raises suspicions. However, if the presentation is atypical, the diagnosis may be missed. We report on a 52-year-old man who presented with a 1-day history of progressively worsening right-sided neck pain spreading to the chest with associated symptoms of autonomic dysfunction. After initial stabilisation, the patient's Glasgow Coma Scale (GCS) score declined, with subsequent CT scan showing an extensive subarachnoid haemorrhage.
