Lumbar Intradural Disc Herniation: A Case Report and Review of Literature

Lumbar intradural disc herniation (LIDH) is very rare and the incidence is reported as 0.04-0.33% of lumbar disc herniations1. LIDH is hardly being diagnosed pre operatively. In recent times with high resolution magnetic resonance imaging (MRI), it is possible to predict exact location of disc in relation to dura. We describe a case with clinical diagnosis of cauda equina syndrome whose MRI lumbar spine was reported as an intradural postero-central L4-L5 disc herniation. At operation, after laminectomy, no disc was found extradurally, so the dura was incised and an intradural disc was found compressing and displacing the roots laterally.
