Recurrent lumbar spinal intradural enterogenous cyst: a case report.

Enterogenous cysts mostly present in the cervical and thoracic region of the spinal canal and have only rarely been observed in the lumbar region. We report here a case of a recurrent enterogenous cyst in the lumbar spinal canal. A 24-year old woman presented with lower back and left radicular leg pain for 1 year. She had been operated on for mass lesion at the same level 10 years ago. Lumbar spine MRI showed a large intradural cyst at L2. Other congenital abnormalities were absent. The cyst was subtotally removed and the patient recovered well. Pathological examination revealed that the lesion was a typical enterogenous cyst.
