Antenatally diagnosed hygroma colli.

A case of prenatally diagnosed hygroma colli is presented. Prenatal diagnosis, characteristic ultrasonic signs as well as problems of differential diagnosis are discussed. The importance of non-elective routine ultrasound screening in the early detection of fetal congenital malformations is emphasized.

Pathomorphological findings of a prenatally diagnosed thanatophoric dwarf.

A case of prenatally diagnosed thanatophoric dysplasia is presented. Other syndromes accompanied by chondrodysplastic tetramicromelia were excluded and diagnosis was based on the narrow thorax, secondary pulmonary hypoplasia and macrocephaly detected by ultrasound and on radiological findings of disturbances of bone formation. At the mother's request labour was induced and radiological, anatomic and histological examination of the newborn confirmed the prenatal diagnosis.
