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. © 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2009
