A.Prof Frank Gaillard and Dr Jeremy Jones et al.

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:

Terminology

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.
