Part 3
We look at the ADC and this is what we see:
The ADC signal is low and so we can be confident that this is true restricted diffusion. The differential is now:
- infarct
- hypercellular tumour
There is associated mass effect, which can be seen in both oedema in an infarct and in a tumour mass. However, there is very strong, homogeneous restricted diffusion and the signal abnormality is in a vascular territory. These point towards it being an infarct. Also, if the onset of symptoms was sudden then an ifnarct is more likely.
Which arterial territory is this infarct in?
Anterior cerebral artery

Middle cerebral artery
Correct answer!
Posterior cerebral artery

Superior cerebellar artery
