Chorionic bump
Chorionic Bump[edit | edit source]
A chorionic bump is an uncommon finding during early pregnancy ultrasound examinations. It appears as a small, rounded protrusion on the gestational sac and is considered a variant of normal early pregnancy development. The clinical significance of a chorionic bump is not fully understood, but it has been associated with an increased risk of miscarriage.
Characteristics[edit | edit source]
A chorionic bump is typically identified during a transvaginal ultrasound performed in the first trimester of pregnancy. It appears as a small, echogenic mass that protrudes into the gestational sac. The size of the bump can vary, but it is generally small compared to the overall size of the gestational sac.
The exact cause of a chorionic bump is not well understood. Some theories suggest that it may represent a small hematoma or a localized area of trophoblastic proliferation. However, these hypotheses have not been definitively proven.
Clinical Significance[edit | edit source]
The presence of a chorionic bump has been associated with an increased risk of adverse pregnancy outcomes, particularly first trimester miscarriage. However, it is important to note that not all pregnancies with a chorionic bump result in miscarriage. Many pregnancies with this finding proceed to term without complications.
The risk of miscarriage in the presence of a chorionic bump is thought to be higher if the bump is large or if there are other abnormal findings on the ultrasound, such as a subchorionic hemorrhage or an irregular gestational sac.
Management[edit | edit source]
There is no specific treatment for a chorionic bump. Management typically involves close monitoring of the pregnancy with follow-up ultrasounds to assess the development of the embryo and the gestational sac. If the pregnancy progresses normally, the chorionic bump may resolve on its own or remain visible throughout the first trimester.
In cases where the chorionic bump is associated with other risk factors for miscarriage, such as maternal age or a history of recurrent pregnancy loss, more frequent monitoring may be recommended.
