Deceased

Natasha Anne Edwards

Demographics

31y, female

Date of death

Finding date

Cause of death

right cerebellar cerebrovascular accident (cerebellar infarction with obstructive hydrocephalus, pressure coning and brainstem compression)

AI-generated summary

31-year-old woman presented with acute onset headache, dizziness, vomiting, facial numbness and speech difficulties. Initial CT brain showed equivocal left temporal hypodensity. Dr B. diagnosed acute migraine/benign positional vertigo and ordered lumbar puncture to exclude encephalitis, delaying neurological consultation. When lumbar puncture returned negative on Saturday afternoon, no reassessment occurred until next morning. The patient had actually suffered vertebral artery dissection causing cerebellar infarction. By Sunday she developed catastrophic cerebellar edema with obstructive hydrocephalus and herniation, causing brainstem compression and death. Expert evidence indicated 60-70% survival likelihood if condition recognized and treated with anticoagulation within 24 hours. Key failures: failure to follow up lumbar puncture results promptly on Saturday afternoon, failure to seek neurological consultation despite confusing presentation, failure to recognize vascular symptoms in young patient, and failure to pursue urgent weekend MRI despite radiologist recommendation.

Contributing factors

  • failure to promptly follow up negative lumbar puncture results on Saturday afternoon
  • failure to seek neurological consultation despite confusing presentation
  • failure to recognize vascular aetiology in young patient with posterior circulation symptoms
  • failure to pursue urgent MRI despite radiologist recommendation for weekend imaging
  • misdiagnosis of presentation as encephalitis or migraine rather than cerebrovascular accident
  • inadequate differential diagnosis considering stroke in young person
  • vertebral artery dissection not recognized as likely diagnosis

Coroner's recommendations

  1. Department of Health should provide further education to all emergency doctors and specialist physicians in relation to signs, symptoms and appropriate clinical management of acute brain attacks in young adults
