A case report of heterochronic presentation of a bilateral tubal pregnancy.

KEY CLINICAL MESSAGE: This paper highlights that diagnosis and treatment of one ectopic pregnancy does not rule out the happening of a second ectopic pregnancy in the same patient concurrently, especially if the patient has rising β-hCG and persistent symptoms.

ABSTRACT: Bilateral tubal pregnancy (BTP) is the most uncommon form of tubal ectopic pregnancy. Complications can lead to maternal morbidity and mortality. We reported a case of left tubal pregnancy and the patient underwent laparoscopic salpingostomy. During the follow-up, the contralateral ectopic pregnancy was discovered and treated with MTX.
