Case 1, image 1: This was a 38 year old man who died of liver failure due to hepatitis C infection. Sections of the basal ganglia demonstrate Alzheimer type II astrocytes with cleared out nuclei.

Case 1, image 2: Another image of cleared out astrocytic nuclei that typify Alzheimer type II astrocytes.

Case 1, image 3: A closer look at the swollen astrocytes.


Alzheimer type II astrocytes are indicative of hepatic encephalopathy and hyperammonemia. The basal ganglia is a good place to look for these reactive astrocytes, however, they can also be seen throughout the brain.
