What is the hamburger sign?
Most common nonlethal skeletal dysplasia.
What is heterozygous achrondroplasia?

What is Aqueductal Stenosis?
What is a modified coronal view?
The normal cardiac axis in the fetal chest.
What is 45-degrees left of midline?
Most common location for an ectopic kidney.
What is the pelvis?
Fetuses with this dysplasia are said to have "telephone receiver"-shaped long bones.
What is thanatophoric dysplasia?
Severe midline fusion abnormality resulting in a monoventricle, abnormal cerebral tissue, fused thalami and absent falx/CSP.
What is alobar holoprosencephaly?
This teratoma is found in the oropharynx and may prohibit fetal swallowing.

This structure is said to have a "candy cane" appearance.

"Hitch-hiker thumb" may be found with this skeletal dysplasia.
