Penny Chapter 25: Fetal Face and Neck

The thickness for the nuchal fold in the second trimester should not exceed

6 mm

Cleft lip and cleft palate may exist with

Amniotic band syndrome, holoprosencephaly, and trisomy 13

A cystic hygroma is the result of

An abnormal accumulation of lymphatic fluid within the soft tissue

The absence of the eyes is termed

Anopthalmia

The most common cause of hypertelorism is

Anterior cephalocele

The measurement obtained between the lateral walls of the orbits is referred to as the

Binocular diameter

Close-set eyes and a nose with a single nostril is termed

Cebocephaly

An abnormal division in the lip is referred to as

Cleft lip

Fusion of the orbits is termed

Cyclopia

A large, mostly cystic mass is noted in the cervical spine region of a fetus. This most likely represents a

Cystic hygroma

All of the following are sonographic features of holoprosencephaly except

Cystic hygroma

Which of the following is also referred to as Trisomy 21

Down Syndrome

Nuchal thickening is most commonly associated with

Down syndrome

An oral teratoma is referred to as

Epignathus

The condition in which there is no nose and a proboscis separating two close-set orbits is

Ethmocephaly

Facial anomalies, when discovered, should prompt the sonographer to analyze the brain closely for signs of

Holoprosencephaly

A cystic hygroma is found in all of the following conditions except

Hydranencephaly

An increased distance between the orbits is referred to as

Hypertelorism

A reduction in the distance between the orbits is referred to as

Hypotelorism

A small mandible is termed

Micrognathia

The most common location of a cystic hygroma is within the

Neck

The most frequently encountered chromosomal abnormality associated with holoprosencephaly is

Trisomy 13

Which of the following is also referred to as Patau syndrome?

Trisomy 13

Micrognathia is a condition found in

Trisomy 18

A group of abnormalities associated with the entrapment of fetal parts and fetal amputations is

Amniotic band syndrome

Macroglossia is most commonly found with

Beckwith-Wiedemann syndrome

The growth disorder syndrome synonymous with organ, skull, and tongue enlargement is

Beckwith-Wiedemann syndrome

An unusual protuberance of the tongue is termed

Macroglossia

The optimal scan plane to visualize micrognathia is

Sagittal

The fetal lip typically closes by

8 weeks
