1

acrania

partial or complete absence of the cranium

2

anembryonic pregnancy (blighted ovum)

gestational sac without an embryo

3

anencephaly

congenital absence of the brain and cranial vault with the cerebral hemispheres missing or reduced to small masses

4

bowel herniation

during the first trimester, the bowel normally herniates outside the abdominal cavity between 8 and 12 weeks

5

cephalocele

protrusion of the brain from the cranial cavity

6

complete abortion

complete expulsion of all products of conception, including embryo and deciduas

7

corpus luteum cyst

a physiologic cyst that develops within the ovary after ovulation, secretes progesterone, and prevents menses if fertilization occurs; may persist until the 16th to 18th week of pregnancy

8

cystic hygroma

fluid-filled structure (often with septations) initially surrounding the neck; may extend upward to the head or laterally to the body

9

ectopic pregnancy

a pregnancy that implants in a location other than the center of the uterus

10

gastroschisis

congenital defective opening in the wall of the abdomen just to the right of the umbilical cord; bowel and other organs may protrude outside the abdomen from this opening

11

gestational trophoblastic disease

condition in which trophoblastic tissue overtakes the pregnancy and propagates throughout the uterine cavity; partial and complete

12

heterotopic pregnancy

simultaneous intrauterine and extrauterine pregnancy

13

holoprosencephaly

failure of forebrain to divide into two cerebral hemispheres, resulting in a single large ventricle with varying amounts of cerebral cortex; has been known to occur with trisomies 13, 15, and 18

14

incomplete spontaneous abortion

pregnancy loss with products of conception remaining in the uterus

15

iniencephaly

a rare neural tube defect in which the brain tissue protrudes through a fissure in the occiput, so that the brain and the spinal cord occupy a single cavity

16

interstitial pregnancy

pregnancy occurring in the fallopian tube near the cornu of the uterus; also known as cornual pregnancy

17

omphalocele

congenital defect of the abdominal wall with protrusion of abdominal contents into the base of the umbilical cord; the cord appears to enter the mass

18

pseudogestational sac

decidual reaction with fluid occurring within the uterus in a patient with an ectopic pregnancy

19

spontaneous pregnancy loss (SPL)

additional term for missed abortion or miscarriage

20

Turner’s syndrome

a nonlethal genetic abnormality; chromosomal makeup is 45XO instead of the normal 46XX or 46XY. Cystic hygroma often is seen in affected fetuses in the first trimester. Survivors tend to be short in stature with low-set ears, webbing of the neck, a shield-shaped chest, and infertility as a result of an endocrine disorder caused by failure of the ovaries to respond to pituitary hormone

21

ventriculomegaly

dilation of the cerebral ventricles without enlargement of the cranium
