What has been the change between CTs?
Low attenuation of both lentiform nuclei, probable infarcts.
Would this fit with the provided clinical history?
Yes - the presenting cardiac arrest with downtime is the probable cause of the hypoxic/ischaemic damage. The dystonic findings on examination also fit with extra-pyramidal disruption.
New from the prior study, there is low attenuation of both lentiform nuclei, compatible with infarcts following a hypoxic/hypoperfusion insult. No cortical or other infarcts.
