Abstract

Chorionic bump (CB) is a convex protrusion from the choriodecidual surface into the first trimester gestational sac. The etiology of CB is unknown, and clinicians face difficulties in diagnosing and managing cases of CB patients due to the small number of reported cases. We present three cases of chorionic bump and relative management in order to contribute to the understanding of a very uncommon ailment and how it may affect pregnancy outcomes. Further studies are needed to improve the knowledge about this rare ultrasound finding.
