Rezumat: Chorionic bump represents a rare abnormality of the gestational sac and, until now, there has been conflicting evidence related to its association with adverse perinatal outcomes. It appears as a bulge from the choriodecidual surface into the gestational sac which often decreases in size with time and rarely persists beyond the first trimester. Our case report presents and discusses a chorionic bump diagnosed early in pregnancy. After adequate counseling, the patient opted for termination of pregnancy; the embryonic karyotype was normal (46, XY). Taking into accoung the relative rarity of this entity, we review the available literature in order to raise awareness on this interesting sonographic finding.
