Herniation of the spinal cord through a dural defect is a rather rare deformity and very easily misdiagnosed as retromedullary occult intraspinal arachnoid cyst or meningocele. The possible origin of the dural defect can be traumatic, iatrogenic or unknown, so in these cases, congenital with great probability. On the thoracal part of the spinal column it shows a rather characteristic and misleading appearance. The anomaly leads to progressive Brown-Sequard syndrome, and the case history can be extremely long. Surgical repair of the dural defect results in improvement, or even complete recovery, if performed in time. These are the facts that emphasize the importance of early diagnosis.
