Stroke Pathology

• Haemorrhage, embolus or thrombosis.

• 'Secondary' stroke may occur with meningitis, bacterial endocarditis, subarachnoid haemorrhage and vasculitis.

• Dissection and cerebral venous thrombosis need to be considered, as anticoagulation is indicated for both (unless a large infarct is established, as there is an increased risk of bleeding). Dissection should be suspected in younger patients, often presenting with severe headache or neck pain ± Horner's syndrome ± seizures after trauma or neck manipulation. Cerebral venous thrombosis may mimic stroke, tumour, subarachnoid haemorrhage or meningo-encephalitis and may present with headache, seizures, focal signs or obtundation.
