ABSTRACT
A 82-year-old woman presented with left buttock pain radiating to the left anterior knee for four weeks. Magnetic resonance imaging of the lumbar spine showed a rim-enhancing mass in the spinal canal at the level of L3 vertebra suggestive of a sequestered disc, which was subsequently confirmed on decompression laminectomy. The clinical and magnetic resonance imaging features of a sequestered disc and its mimics are discussed.
