Prenatal pathology refers to an abnormality or disorder found in a fetus during pregnancy. Synonyms for prenatal pathology include fetal anomalies, embryonic abnormalities, fetal diseases, and antenatal disorders. These conditions range from minor malformations to life-threatening defects. Important prenatal tests, such as ultrasounds and amniocentesis, can detect some types of prenatal pathology. Early identification of fetal abnormalities can enable healthcare professionals to provide appropriate treatment and counseling for affected families. In some cases, prenatal pathology can be fatal, and families may be faced with difficult decisions about how to proceed with the pregnancy. Nonetheless, knowledge of prenatally-diagnosed conditions can help parents better prepare for the birth and care of their child.
