I appreciate your query.
Basically the problem is not that the head growth is abnormal, but the growth of the femur ( limbs ) is lagging behind.
Skeletal dysplasias may refer to any of over 350 distinct disorders. Differentiating them before birth is difficult. The consequences also range from simple dwarfism to life threatening complications.
Many of these are inherited, and it is possible to test for them by prenatal diagnosis. Any fetus showing femora or humeri length measurements less than 5th centile or −2 SD from the mean in the second trimester (
The worrying aspect can be lethal ( non compatible with life ) skeletal dysplasias. Lethality occurs in most skeletal dysplasias as a result of a small chest circumference and resultant pulmonary hypoplasia. ( non development of lungs )
Milk dilatation of the lateral ventricle - In most cases, it probably represents a normal variant. In other cases, mild enlargement of the lateral ventricles is a marker of a varied group of abnormalities of the brain, as well as other chromosomal anomalies.
Since you have two abnormal findings, particularly skeletal dysplasia, please get yourself thoroughly evaluated by expert sonologist and geneticist.
Be prepared for extensive work up of the baby after birth.
The placenta is the organ that connects the developing fetus to the uterine wall of the mother, and allows nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. In humans, the placenta averages 22 cm and weighs approximately 500 grams (1 lb). It has a dark reddish-blue or crimson color. It connects to the fetus by an umbilical cord .
Please proceed for complete sonological and genetic work up of your baby, in view of skeletal dysplasia.
All the best.
