Heterotopic pregnancy after 2 prior ectopic pregnancies: a case report.

BACKGROUND: Heterotopic pregnancy is a rare occurrence, with spontaneous pregnancy often unsuspected and associated with delayed diagnosis. When previous ectopic pregnancy has been treated, future pregnancy is associated with an increased risk for ectopic pregnancy and potentially heterotopic pregnancy. Conservative treatment for ectopic pregnancy with either surgery or methotrexate leaves the patient with hope for potential future fertility, especially when assisted reproductive technology is not available. CASE: A woman who had been treated for ectopic pregnancy in both fallopian tubes presented with a spontaneous heterotopic pregnancy. CONCLUSION: Heterotopic pregnany may occur after treatment of previous ectopic pregnancy and may lead to a successful outcome when diagnosed and treated appropriately.
