The hair collar sign as a marker for neural tube defects.

The hair collar sign has been described as a marker of cranial dysraphism, including encephaloceles, meningoceles, and heterotropic brain tissue. This report describes a male born with a hair collar sign who subsequently was found to have a Klippel-Feil anomaly, diastematomyelia, multiple segmental spine and rib anomalies, and a translocation between chromosomes 1 and 4; t(1;4) (q44;q10). While not previously documented, spine abnormalities may be an associated abnormality with the hair collar sign.

The majority of therapeutic modalities have been extensively investigated and relevant basic science and randomized well-controlled clinical studies addressing the efficacy of therapeutic modalities are emphasized.
