Simultaneous bilateral tubal pregnancy after intracytoplasmic sperm injection treated by conservative medical treatment - Interest of sonographic follow-up

We describe a case of early bilateral tubal pregnancy diagnosed by transvag inal ultrasonography after intracytoplasmic sperm injection (ICSI) and embr yo transfer (ET). A follow-up by transvaginal sonography was done with a sy stematic second scan (5 days) after the first diagnosis of left tubal ectop ic pregnancy in case of assisted conception procedure. This follow-up sonog raphic strategy permitted us to perform a conservative treatment for this c ase of spontaneous bilateral tubal pregnancy by two consecutive (left then right) in-situ methotrexate injections under vaginal ultrasonographic guida nce without any complications.
