Isolated filar cyst on lumbar spine sonography in infants: a case-control study.

Background: Simple cysts found within the filum terminale of infants on lumbar spine sonography are relatively common, but no study has established their clinical significance.

Objective: To obtain information on the sonographic features of isolated filar cysts and determine their clinical significance in comparison with age- and sex-matched controls.

Materials And Methods: We performed a retrospective review of 644 consecutive spine sonograms in patients younger than 8 months.
