AN UNEXPECTED TRIPLET HETEROTOPIC PREGNANCY AFTER REPLACEMENT OF 2 EMBRYOS

We report a case of a triplet heterotopic pregnancy consisting of an i ntrauterine monozygous twin pregnancy and a tubal pregnancy after repl acement of only two embryos in an in-vitro fertilization cycle with do nor spermatozoa. This case demonstrates that sonographic demonstration of two intrauterine pregnancies after transfer of two embryos does no t exclude the presence of an ectopic pregnancy, As both heterotopic pr egnancy and spontaneous monozygotic twinning are more frequent after t he use of assisted reproductive techniques, this combination, although extremely rare, must be kept in mind, especially in older patients wi th pre-existing tubal damage.
