Coexisting ectopic and intrauterine pregnancies: a case report.
BACKGROUND
The simulated presence of intrauterine and extrauterine pregnancies is a rare condition. Diagnosis is difficult, accomplished on grounds of strong suspicion (as in assisted reproductive treatment cases), on the presence of predisposing factors (pathology of salpinx) or as a coincidental finding in the emergency room when a patient presents after an elective or spontaneous abortion. An intrauterine pregnancy may be discovered in a patient who presents with ectopic pregnancy.


METHODS
A 40-year-old multigravida was diagnosed with coexisting extrauterine and intrauterine pregnancies when she presented with a right ectopic pregnancy in the emergency room. The patient underwent partial right salpingectomy and an elective abortion.


CONCLUSIONS
Patients who present with acute pelvic pain must be investigated for coexisting ectopic pregnancy even though they have a proven intrauterine pregnancy. Such an investigation is even more important if the patient is undergoing assisted reproductive treatment. In patients who have had spontaneous or elective abortion, especially in cases of a gestation <4 weeks, the differential diagnosis should include coexisting ectopic pregnancy. Failure to diagnose this condition can have serious consequences.
