Presentation
5 days post cardiac arrest with prolonged downtime. Persistently reduced GCS of 11.
Patient Data
Loss of CT visibility of the caudate and lentiform nuclei bilaterally (hypoattenuation) 5 days after a cardiac arrest consistent with hypoxic-ischemic brain injury.
On day of cardiac arrest these is no appreciable abnormality on CT. Specifically the grey-white differentiation of the basal ganglia is preserved.
Hypoxic-ischemic brain injury. Preserved caudate head grey matter density on day 1 (yellow arrows) compared to loss of caudate head density on day 5 (blue arrows) with absence of differentiation between the nuclei and the adjacent internal capsule white matter.
Case Discussion
Loss of CT visibility of the caudate and lentiform nuclei (hypoattenuation) 5 days after a cardiac arrest consistent with hypoxic-ischemic brain injury.
