Borderzone infarct

Case contributed by Assoc Prof Frank Gaillard


CT obtained post fall.

Patient Data

Age: 70 years
Gender: Male

In addition to bilateral chronic small vessel ischemic change, on the left there is patchy cortical infarction in a borderzone distribution.


Single image through the left internal carotid artery demonstrates a high grade stenosis. 

Case Discussion

Care must be taken when dismissing change as chronic small vessel ischemia, and evidence for cortical infarction should be sought. In this case the pattern of cortical involvement suggested a borderzone (watershed) infarct and a CTA confirmed the presence of a high grade left sided stenosis.
