Symptomatic Epidural Gas Cyst Associated With Discal Vacuum Phenomenon

Abstract

Although the vacuum disc is considered a common imaging finding of no or not much pathologic significance, occasionally intradiscal gas may leak into the spinal canal. Detection of an epidural gaseous collection at the same level with a vacuum disc strongly suggests a communication between the intervertebral disc and the epidural space. Epidural gas collections can be implicated as a possible cause of radicular symptoms and should be considered in the differential diagnosis of lumbar radiculopathy.

Gas-Containing Disc Herniations: Dual Nerve Root Compression at a Single Disc Level

“…7,10,11) Both T 1 -and T 2 -weighted MR imaging show gas as low intensity (signal void). Epidural gas can be distinguished from gas in a herniated disc as the former assumes the contour of the epidural space, whereas the latter is surrounded by the soft tissue of the herniated disc as seen on CT. 8) In our case, CT showed gas in the L3-4 intervertebral disc space, in the right extraforaminal region, and at the L3-4 spinal canal level. MR imaging showed the Neurol Med Chir (Tokyo) 52, September, 2012 Disc Herniations Containing Gases at the Single Level Dual Regions disc as a signal void in the spinal canal at the L3-4 level communicating with the intervertebral disc, and a lesion without any signal void in the extraforaminal region without communication with the intervertebral disc.…”

Pseudokystes gazeux lombaires épiduraux, une cause rare de douleur radiculaire sévère

“…Les phénomènes de dégénérescence discale avec vide discal sont fréquemment observés dans les examens radiologiques du rachis chez la personne âgée et ne sont pas considérés comme cliniquement significatifs [1][2][3]. Cependant, le gaz intradiscal peut faire hernie dans l'espace épi-ou intradural, cette collection gazeuse intracanalaire peut for-ଝ Ne pas utiliser, pour citation, la référence franç aise de cet article, mais sa référence anglaise dans le même volume de Joint Bone Spine mer des pseudokystes [1][2][3][4].…”

Vertebral Pneumatization

“…Less than 15 human cases were found in the literature over the last 15 years involving pneumatization at the cervical level [5,10,14,15,17,19,20] and most were less than 5 mm in size. Atypical pneumatization occurs more often in the skull [17] and the sacrum or lumbar spine [1,2,13] and of course secondary pneumatization of vertebral discs (vacuum phenomena) or facet joints due to degeneration is common [1,2,8]. potentially severe differential diagnoses, such as infection, trauma and gas-building metastatic lesions can be easily differentiated.…”
