MRI Diagnosis Of Intradural Lumbar Disc Herniation. Report Of Three Cases With Review Of Literature.

Abstract

With recent improvements in magnetic resonance imaging (MRI) it has become possible to preoperatively diagnose intradural migration of disc fragments. Apart from the classical ring enhancement of the intradural fragments on gadolinium contrast MRI, there are several other imaging features that may help in diagnosis of this rare condition. We report three cases of intradural lumbar disc herniation and review literature with emphasis on MR diagnosis.
