Introduction
➢Focal neurological deficit
➢ Ischaemic V. Haemorrhagic
➢Modifiable risk factors
➢Symptoms depend on the area of the
brain affected
Case Study
❏ 79yo female
❏ Left sided weakness
❏ Post trauma
❏ Past history MCA territory stroke
❏Rule out: haemorrhagic stroke, ischaemic
stroke, traumatic haemorrhage
❏ 2x CTs performed
Stroke Imaging
➢What imaging is appropriate?
➢How does the imaging contribute to the
diagnosis?
➢How does the imaging contribute to the
management?
Radiological signs
➢ Earliest
○ Hyperdense segment
of a vessel
○ Visible thrombus/
embolus

Radiological signs
➢Hyperacute○ Loss of grey-white matter differentiation
○ Cortical hypodensity
○ Dependent upon the occlusion location and
whether collaterals are present
Radiological signs
➢Week two/three○ CT fogging - decrease in swelling and
increased attenuation of the cortex
○ Confusing to interpret, can lead to a missed
diagnosis
Treating an ischaemic stroke
➢Rapidly restore cerebral blood flow○ Thrombolysis
○ Thrombectomy
➢Rehabilitation
