Abstract

The chorionic bump, an irregular, convex bulge of the choriodecidual surface into the gestational sac (GS), is a recently described, uncommon abnormality of the 1^st-trimester GS and is associated with a guarded prognosis for early pregnancy. The case of this 42-year-old female demonstrates a previously unreported relationship: a transvaginal sonographic finding of a chorionic bump associated with a spontaneous tubal ectopic pregnancy. This might support the hypothesis that the chorionic bump represents a small hematoma that bulges into the GS.
