A case of heterotopic pregnancy in the absence of risk factors. A brief literature review.

OBJECTIVE

To reinforce the risk of heterotopic pregnancy in a natural cycle when intrauterine pregnancy and abdominal pain co-exist.

METHOD

A single case report with a literature review.

RESULTS

Our case was associated with significant haemorrhage, laparotomy and salpingectomy. The obstetric outcome was favourable in this case. The literature review demonstrates the diagnostic difficulties as well as treatment options.

CONCLUSIONS

Sonographic diagnosis of a heterotopic pregnancy is not always possible. Patients with abdominal pain and intrauterine pregnancy should heighten the clinician's suspicion of a heterotopic pregnancy.
