Advanced and unsuspected secondary abdominal pregnancy misdiagnosed before laparotomy.

A case of advanced secondary abdominal pregnancy is presented. It happened in a multiparous patient, a heroin addict and with a previous secondary amenorrhea. In spite of having been controlled through the whole pregnancy, the ectopic pregnancy was not diagnosed until a laparotomy was performed, several days after fetal death. After full extraction of the fetus and placenta, followed by left adnexectomy, the postoperatory evolution was normal. Hormonal and echographic studies and fetal monitorings are provided, and the diagnosis and treatment are discussed.
