Although intradural disc herniations are rare, they should be kept in mind because of the difficulties in diagnosis and treatment. The incidence of intradural disc herniation is between 0.27% and 0.33% in all discs. In this article, a patient who received surgery with diagnoses of spondylolisthesis and lumbar disc herniation, seen to be an intradural disc herniation during the operation, is discussed in the light of the literature. Magnetic resonance imaging (MRI) should be taken in suspected cases.
