What is prominent epidural fat?

Prominent epidural fat refers to an increased amount of fat in the epidural space, which is the area between the outer layer of the spinal cord and the surrounding bony vertebrae. This condition can be seen on imaging studies, such as MRIs, and may be associated with conditions like obesity, aging, or certain spinal pathologies. While prominent epidural fat itself is typically asymptomatic, it can sometimes contribute to spinal canal narrowing or other complications.
