Lumbar epidural gas is a rare phenomenon where gas locules are observed within the central canal of the lumbar spine. It can arise from a number of factors:

due to regional degenerative disc disease with or without dorsal epidural disc migration: thought to be from gas leaking from the disc space to the epidural area through the tears of annulus fibrosus, occurring mostly with herniated fragments ⁴
traumatic pneumorrhachis
postoperative pneumorrhachis
from a degenerative spinal synovial cyst
from a gas containing herniating regional ganglion cyst
