Differentiating between acute and chronic infarction on a CT brain is an important skill for many health professionals particularly in the emergency setting:
- pathology
- acute: cytotoxic edema
- chronic: encephalomalacia; Wallerian degeneration
- hypoattenuation
- acute: more dense than CSF
- chronic: CSF density
- mass effect
- acute: positive (volume gain)
- sulcal / ventricular effacement
- midline shift / herniation
- chronic: negative (volume loss)
- widened sulci
- ex vacuo dilatation of ipsilateral ventricle
- acute: positive (volume gain)
