This is about a 71-year-old male. Psychiatrist said that a plain CT scan and another CT scan should be taken with contrast, but after four attempts they could not create channel in his veins, so contrast CT scan of the brain was not done.

Cortical sulci, Sylvian fissure, basal cisterns at places and supratentorial ventricles are mildly prominent.
Lacunar infarct in right claustrum.
Mild bilateral cerebral cortical atrophy (age-related).
