Pachymeningeal enhancement
Updates to Article Attributes
The pachymeninges consist of the Pachymeningeal enhancement, also known as dura mater-arachnoid enhancement 4, refers to a dural and outer layer of the arachnoid mater and cover the convex dural surface of the brain.
Pachymeningeal (dural)enhancement refers to a pattern of enhancement seen following contrast administration and occurs in a number ofsome conditions listed above:
- infection
-
intracranial tumour
- metastases
- intracranial hypotension
-
post-operativepostoperative states - idiopathic pachymeningitis
- cerebral venous thrombosis
- neurosarcoidosis
- extramedullary haematopoiesis
- rheumatoid arthritis
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.
