Lumbar split cord malformation and Klippel-Feil syndrome

Abstract

The authors report a patient with type II split cord malformation (SCM) and Klippel-Feil syndrome (KFS). Considering our review of the medical literature and present case report, we believe lumbar SCM and KFS in the same patient not to be coincidental findings but rather embryologically related entities. We propose that KFS in at least one of its phenotypes represents a forme fruste of occult spinal dysraphism.
