Alcohol is the most frequent and most important teratogenic noxa for the embryo and fetus. It may lead to deformation of all cells and organs. A case of Klippel-Feil anomaly associated with fetal alcohol syndrome is described. The diagnosis of Klippel-Feil anomaly, even a late diagnosis made on the basis of rare deformities, is very important as the affected patients are at a high risk of alcoholism. The combination of Klippel-Feil anomaly with numerous other syndromes and deformities suggests a basic general disorder of skeletal maturation. Diverse cases of Klippel-Feil anomaly possibly originate, in reality, in an unrecognized fetal alcohol syndrome.
