Dural enhancement

Pachymeningeal enhancement, also known as dura-arachnoid enhancement 4, refers to a dural and outer layer of arachnoid pattern of enhancement seen following contrast administration and may occur in the conditions listed below:


It is important to note that the thin arachnoid membrane is attached to the inner surface of the dura mater, and so the pachymeningeal pattern of enhancement can also be described as a dura-arachnoid enhancement 3

On the other hand, the enhancement of the brain surface is also called as pial or pial-arachnoid enhancement, often referred to as leptomeningeal enhancement 3.
