Incidence of perineurial cysts in relation to the vertebral/spinal level.

Absolute number of MR examinations per selected spinal region: cervical –221 (146/75; female/male), thoracic –108 (69/39), thoraco-cervical –36 (25/11), thoraco-lumbar –55 (35/20), lumbo-sacral –422 (268/154).
aabsolute number of perineurial cysts/total number of examinations in which the proper part of vertebral column was evaluated.
brelative incidence (%) of perineurial cysts in relation to the total number of the proper level of vertebral column.
ceach patient may be seen more then once in table since some multiple cysts were seen on adjusted parts of the vertebral column (e.g., cervical and thoracic, thoracic and lumbar, lumbar and sacral).
