Cerebral venous thrombosis (CVT) directly causing subdural haemorrhage (SDH) is a rare entity. We present a case of an 18-year-old female patient who presented with severe occipital headache. Neuroimaging showed acute SDH and CVT. She was eventually discovered to have underlying protein C deficiency. She was treated with anticoagulation and made an uneventful recovery. We aim to highlight the epidemiology, risk factors and aetiopathogenesis of CVT. We have included a literature review of previously described 13 case studies/reports describing SDH associated with CVT and a brief discussion of the dilemmas associated with management.

  • headache (including migraines)
  • neuroimaging
  • stroke
  • warfarin therapy
