Overview
CT is usually normal. Late findings may include cerebral edema and decreased attenuation in the hippocampus, brain stem, basal ganglia, and periventricular white matter.
CT
If there is enough time to take a CT scan of a suspected rabies patient, there are a few things that can be looked for.
- A CT scan may display focal or diffuse areas of decreased attenuation in the hippocampus, brain stem, basal ganglia, and periventricular white matter.
- There is also the possibility of pontine hemorrhages being reported.
- In advanced cases, it is possible to see diffuse cerebral edema[1].
Early findings:
- Usually normal
Late findings:
- Cerebral edema may be seen
