Hypoxic-ischemic brain injury

Case contributed by Dr Andrew Dixon

Presentation

5 days post cardiac arrest with prolonged downtime. Persistently reduced GCS of 11.

Patient Data

Age: 45
Gender: Male
CT

5 days post cardiac arrest

Loss of CT visibility of the caudate and lentiform nuclei bilaterally (hypoattenuation) 5 days after a cardiac arrest consistent with hypoxic-ischemic brain injury

CT

On day of cardiac arrest

On day of cardiac arrest these is no appreciable abnormality on CT. Specifically the grey-white differentiation of the basal ganglia is preserved.
