Hi, Let me see if I can explain this report for you a bit. That may help you understand what is going on.

"There is low attenuation area in the right frontal lobe and posterior left frontal lobe due to small area of encephalomalacia."

This is the line that must be bothering you. What it means is that both of the frontal lobes have lost alot of the neurons that are supposed to be there. This changes the density and appearance on CT scan. This is known as Encephalomalacia.

To answer you more directly, yes, these are the typical findings in cerebral atrophy. I can't tell if the process is ongoing or has halted from any of the findings given here. I would need an earlier scan to look at the changes through time.

Though unfortunately, most cases of cerebral atrophy will progress with age.

I hope this helps. If you would like a more personalized discussion, you can use our "Ask a Specialist" services and we will get back to you right away.

Take Care, Vinay
