Leptomeningeal enhancement refers to a diffuse or focal gyriform or serpentine enhancement that can be seen in the following conditions:

Diffuse
Focal

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.
