Incomplete Currarino triad as an embryological variant - Case report and review of the literature

Abstract

Currarino triad is a rare embryological complex of congenital caudal anomalies, including anorectal malformation, sacral osseous defect, and presacral mass, that results from abnormal separation of the neuroectoderm from the endoderm. The authors present an unusual case of a patient who had, in addition to the classic features of this syndrome, holocord syringomyelia, low conus medullaris, and tethered cord demonstrated by magnetic resonance imaging. They also discuss the embryological significance of this clinical entity and briefly review the relevant literature.
