A case of pseudoisochromosome 18q of prezygotic origin and a case of isodicentric chromosome 18 of postzygotic origin are presented to validate the differentiation between a true isochromosome and a pseudoisochromosome. This differentiation may be useful in elucidating the mechanism of the origin of an isochromosome.
