chorionic bump vanishing twin
What is a chorionic bump in the uterus?
A Chorionic Bump (CB), which has been identified as “an irregular, convex bulge from the choriodecidual surface into the first-trimester gestational sac,” was first reported by Harris et al.
In some cases, a gestational sac is not seen at all.
The most common reason for this is inaccurate dates or it is simply too soon.
If a gestational sac is not seen on a follow-up scan, or if your hCG levels indicate one should be seen, it can be a sign of a miscarriage or ectopic pregnancy.
Can chorionic bumps cause miscarriage?
Wax et al. reported that the chorionic bump is associated with a four-time increase in miscarriage incidence.
Arleo et al. reported that in otherwise normal pregnancies, the rate of live births was 83% with a single chorionic bump [7-8].
Can a chorionic bump go away?
A chorionic bump is an increasingly recognized ultrasound finding in first-trimester scans, which has been associated with early pregnancy loss.
In ongoing second-trimester pregnancies, however, chorionic bumps usually resolve over time with no deleterious effect on the fetus.
