These images are from an 76 year old man, who
suffered a severe fall 6 months before seeking medical
attention. He complained of memory loss, and
had been depressed since the death of his wife.
He had a history of alcoholism, with several hospital
admissions for gastrointestinal bleeding. |
Note the large fluid collection displacing the brain.
It is white
on T2-weighted images, and, of course, non-perfused on SPECT.
The lateral and third ventricles are a bit large, partly due to the
effects of age and partly to the effects of alcohol abuse. The
mammillary bodies are small in this case
compared to the normal,
a finding commonly seen in alcoholics.
