This case was diagnosed in utero with multiple congenital anomalies including occipital encephalocele, mega\u2010cisterna magna, mesomelic shortening, and clubfeet. An analysis of GTG\u2010banded chromosomes of 20 metaphase cells was performed. Female karyotype [47,XX, +i(20)(p10)] was revealed in all cells. Pure tetrasomy 20p was confirmed using fluorescent <jats:italic>in situ<\/jats:italic> hybridization (FISH) with a telomere probe for chromosome 20p in all seven metaphase cells. The pregnancy was terminated because of associated multiple anomalies and severe oligohydramnios. The postmortem examination confirmed the prenatal diagnosis.
