Chorionic bump in a pregnant patient with a history of infertility

Chorionic bump is a rare condition in the first trimester of pregnancy. It appears as a bulge from the choriodecidual surface into the gestational sac. So far, there have been no ultrasound or clinical markers that can predict a difference in outcome

We report a case of a pregnant woman with history of infertility, diagnosed in the first trimester with a chorionic bump. It disappeared spontaneously at 23 weeks of gestation. The pregnancy went well and she delivered a healthy baby.

The aetiology and clinical significance of the chorionic bump remains unclear.
