Clinical question: Hypoxic encephalopathy. Signs and symptoms: Cardiac arrest. Non-infused CT of brain.Examination again demonstrates a hematoma in the left thalamic region. Poorly defined borders of hematoma are consistent with breakdown. The overall size of this hematoma remains similar to prior exam of 24 hours earlier. Very extensive surrounding vasogenic edema with associated mass effect is again identified and with no appreciable change. Edema appears to extend inferiorly from the thalamus into the left cerebral peduncle. Mass effect on the third ventricle and midline shift remains similar to prior exam. Mild guided patient of lateral ventricles remains similar. Minimal amount of blood within bilateral occipital horns remain stable. Extensive periventricular and subcortical foci of low-attenuation although nonspecific however there are concerning for small vessel disease of indeterminate age.Further follow-up with an MRI is recommended.
Overall stable exam since prior study.
