The ultrasonogram was done at approximately 15 weeks gestation and shows two orbits, a mouth, and a central nose, but there is clearly no forehead and no cranial contents. Even a relatively inexperienced sonographer using average equipment available in the early 1990s would be able to pick up anencephaly. Anencephaly is, of course, incompatible with life and is the only condition for which a termination of pregnancy is generally permissible at any gestational age.
