What is the most likely diagnosis? What conditions should be included in the differential diagnosis?(Answered)

A 24-year-old G0 woman comes to the emergency department (ED) complaining
of left lower abdominal pain and intermittent vaginal bleeding. The patient reports
being sexually active with her husband and states that she only intermittently
uses contraception. She denies any medical problem but does state that she had a
chlamydial infection 7 years ago. Her last menstrual period was 6 weeks ago. On
physical examination, the patient is in mild discomfort, with a heart rate of 98/min
and a blood pressure of 130/85 mm Hg. Pelvic examination is remarkable for cervical
motion tenderness and a closed cervical os. Her β-human chorionic gonadotropin
(β-hCG) level is 2000 mIU/mL

Right Answer Is : This patient most likely has an ectopic pregnancy in her left fallopian
tube. The positive serum β-hCG suggests that this patient is pregnant,
and her clinical symptoms of left abdominal pain and abnormal uterine
bleeding suggest an abnormal pregnancy.
