Unruptured alive tubal ectopic pregnancy at 13 weeks of gestation: a case report; review of literature and management options.
Pak J Surg Jan ;36(4):354-7.

A progressive second-trimester tubal ectopic pregnancy came across infrequently because almost all ectopic pregnancy has diagnosed at an early stage. The present case was a 37-years old lady presented with 13+4 days gestational amenorrhea and with lower abdominal pain, vomiting and loose motion. The Bedside ultrasound revealed 13 weeks size of an extrauterine gestational sac with a single viable fetus, and moderate blood in a pouch of Douglas. The differential diagnosis was either an abdominal versus a complicated tubal pregnancy. The patient had a successful laparotomy and left salpingectomy done. So, it is an unusual case of large unruptured alive ectopic pregnancy at 13 weeks of gestation.
