A giant neck mass that can grow to obstruct the airway
Abnormal closure of lip and/or palate
Opening in the diaphragm, a muscle between the abdomen and chest, which allows the abdominal contents to go into the chest causing the lungs to be poorly developed
Failure of the main airway (trachea) to connect to the throat, causing abnormally large cystic lungs and the inability of air to enter the lungs once the child is born
Fetal lung lesions often referred to individually as: bronchopulmonary sequestration (BPS), Congenital pulmonary airway malformation (CPAM), congenital cystic adenomatous malformation (CCAM), congenital lung emphysema (CLE) or congenital lung overinflation (CLO), or hybrid lesions
Twins which are joined to each other, at the head, chest, abdomen, pelvis, or a combination of these areas
Blocked or missing part of the esophagus. The most common is one where the lower part of the esophagus connects to the airway (trachea) known as a tracheoesophageal fistula (TEF)
Abnormal opening in the abdomen that allows the bowels to come outside of the body
Such as trisomy 13, trisomy 18, trisomy 21, DiGeorge syndrome, and many others
Abnormal increase of cerebral spinal fluid around and in the cavities of the brain
When the voice box (larynx) doesn't develop properly
A condition that doesn't allow the bladder to empty properly. This not only damages the kidneys but causes a low volume of fluid around the fetus leading to underdeveloped lungs
An opening in the umbilical cord which allows some of the abdominal contents to herniate out into a covered sac. Sometimes this can be large often allowing the liver to herniate out into the sac as well
Rare abnormal tumor around the heart that can compress the heart causing it to fail
Abnormal collection of fluid in the chest around one or both lungs
Tumor that grows off of the tailbone of the fetus, some of which can get very large causing the child to go into heart failure
When one twin in the womb grows much smaller than the other because it isn’t getting an equal share of nutrients and blood flow from the placenta
Where a fetus' bones and cartilage develop abnormally in the womb, leading to differences in growth, shape, and strength of the skeleton.
A narrowed, blocked or missing part of the intestine. Can be in the duodenum, jejunum or ileum. Other conditions that block the intestine can also have a similar presentation, like meconium ileum or meconium plug often associated with cystic fibrosis
Also known as a myelomeningocele or MMC, is an abnormal opening in the spine of the fetus where the spinal cord is exposed leading to neurological problems depending on the size and location
A condition in identical twins who share a placenta, where one twin becomes anemic (too few red blood cells) and the other becomes polycythemic (too many red blood cells) because of an uneven blood exchange between them
A rare condition in identical twins sharing a placenta, where one twin’s heart pumps blood not only for itself but also for the other, non-developing “acardiac” twin, which can put the healthy twin at serious risk
A condition in identical twins who share a placenta, where blood flows unevenly between them—causing one twin to get too much blood and the other too little—putting both at risk
An abnormal collection of vessels (arteries, veins, capillaries, or lymphatic) which form a mass. This can occur throughout the body, sometimes leading to disfiguration or compression of organs
