-Recognize cystic lesions of the spinal channel according to their localization and dependency. -Review and update the current classifications for the meningeal cystic lesions,
taking a close look at the etiology and therapeutic implications.
Since the appearance of magnetic resonance imaging (MRI),
the diagnostic rates of spinal cystic lesions have increase.
Base on anatomical presentation,
the most common lesion site is arachnoid.
Nabors et al introduced a classification for arachnoid cysts that distinguished extradural cysts not containing nerve roots (type I) from extradural cysts containing nerve roots (type II) and intradural arachnoid cysts (type III).
But Nabor’s classification does not account for all pathologies...
Findings and procedure details
Spinal cysts related to the intervertebral disc. Discal cyst: A discal cyst is a rareextradural cyst which communicates with the adjacent intervertebral lumbar disc.
it appears as a ventrolateral,
extradural cystic mass attached to a lumbar intervertebral disc (Fig 2) as well as rim enhancement of its wall on contrast-enchanced MRI.
the lesion spreads into the lateral recess. They are believed to occur due to traumatic disruption of the annulus with accumulation of...
There are a great variety of spinal cyst types,
diverse classification and diverse mechanism reviewed in the literature.
In this article we try to summarize a creditable as well as simple classificationfor main kinds of spinal canal cysts in order to facilitate the therapeutic options for each case.
