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
