leiomyoma
common solid mass associated with pregnancy?
With a normal pregnancy, the first structure noted within
chorionic sac
the decidualized endometrium is the:
Fertilization typically occurs within ____ after ovulation. 24 hours
What term is used to describe the condition of a patient
with vaginal bleeding and a closed cervix prior to 20 weeks threatened AB
gestation?
it is a good indicator of possible chromosomal abnormal-
ities
What is the significance of the measurement in this ultra-
sound image?
A 24-year-old woman with a positive pregnancy test result
and pelvic pain is seen for an ultrasound. She has a history
of pelvic inflammatory disease. The ultrasound reveals a
ectopic pregnancy
uterus containing an anechoic sac that lacks a double
decidual sac sign with a moderate amount of cul-de-sac
fluid. This is most suspicious for which of the following?
During a 12-week sonogram, bilateral echogenic struc-
tures are noted within the lateral ventricles of the fetal choroid plexus
cranium. These structures most likely represent:
the decidual portion superficial to the blastocyst project-
The decidual capsularis is best described as
ing into uterine lumen
Which sonographic finding is associated with an abnor-
embryo with a calcified yolk sac
mal pregnancy?
What is the most accurate parameter in dating the fetus
crown rump length
throughout the pregnancy?

likely diagnosis at this gestational age?
The CRL measurement may be used up to the -------
12th
gestational week
The first structure noted within the gestational sac is the: yolk sac
During a first-trimester sonogram, you note a round, cys-
tic structure within the fetal head. This most likely repre- rhombencephalon
