1. Intervertebral disc pathology can have unusual manifestations which interpreting radiologists may encounter and should be able to recognize. 2. The differential diagnosis of an intraspinal extradural cyst includes a discal cyst. 3. Intradural disc herniation, spinal CSF leak due to disc/osteophyte, & ventral cord herniation at a disc level: a spectrum of disease with similar pathology. 4. The contour and position of thoracic cord should always be scrutinized to exclude ventral spinal cord herniation, a treatable cause of myelopathy. 5. The differential diagnosis of a dorsal epidural mass includes a migrated/sequestered dorsal disc fragment. 6. Disc herniations in unusual locations/varieties typically peripherally enhance (intradural, dorsal epidural, extreme lateral, discal cyst).
