Meningoceles and the tethered cord syndrome

Abstract

This study shows that there is a relationship between simple meningocele and the tethered cord syndrome. Two groups of patients were examined: the first comprised patients presenting with neurological abnormality at some period after initial closure of a simple meningocele, and the second group (18 patients) had elective myelography after closure of a simple meningocele in the neonatal period (in 17 of the 18 cases). Of these 18 cases. 10 showed an intradural abnormality, and all underwent surgery confirming their myelographic diagnosis. The conclusion is drawn that after closure of a simple meningocele in the neonatal period, patients should have elective myelography in the first 12 months of life to determine whether or not the tethered cord syndrome is likely to develop during the period of growth.
