[Lumbosacral dermal sinus as entry point of purulent meningitis. Report of 3 cases]

Abstract

Defects of neural tube closure, although minimal, can provide access for infections of the central nervous system. All skin alterations in rear middle line of the body, however, minimal, must be carefully investigated as they could give access to bacterial meningitis. We present three new cases of dermal lumbosacral sinus which went unnoticed in the neonatal period later becoming the access point for bacterial meningitis.
