Coexistent intrauterine and ectopic pregnancy: a reevaluation.

Abstract

Retrospective analysis of ectopic pregnancies occurring in the past 36 months at the Beth Israel Hospital yielded two cases of concomitant intra- and extrauterine gestation. The incidence of coexistent intrauterine and ectopic pregnancy in this sample is 1/6,778, or 0.015% of all pregnancies. We report these cases and two additional cases from another institution (Leonard Morse Hospital). We postulate that simultaneous intrauterine and ectopic pregnancy may be more common than previous statistics indicate.
