Intradural disc herniation mimicking a spinal tumor [Spinal tümörü taklit eden İntradural disk herniasyonu]

Intradural disc herniation is a rare pathological condition. the exact pathogenesis of intradural disc herniation is not known yet. although contrast-enhanced mri scans are useful to differentiate a herniated disc from other lesions,misdiagnosis is common. we describe a 43- year-old man with a 5 year history of low back and right leg pain. he reported a sudden exacerbation of these symptoms for a month. magnetic resonance imaging revealed a masslike lesion with peripheral contrast enhancement at the level of l5-s1. right l5 hemilaminectomy was performed,and intradural disc fragment was removed after longitudinal durotomy. intradural disc herniation must be kept in mind in the differential diagnosis of intradural mass. © 2014 ege university press. all rights reserved.
