Concurrent Interstitial Ectopic Pregnancy and Appendicitis: A Case Report
Authors:  LCDR R. Lee Biggs, MC, USN, CAPT Everett F. Magann, MC, USNR, and CDR John D. O‘Boyle, MC, USN
BACKGROUND: Concurrent ectopic pregnancy and acute appendicitis is rarely encountered. Since 1960, only 22 cases have been reported. No case of concurrent interstitial ectopic pregnancy and appendicitis has ever been reported.

CASE: A 24-year-old, African American woman, gravida 4, para 3, had a right interstitial ectopic pregnancy. She was managed as an inpatient with parenteral methotrexate and her b-human chorionic gonadotropin level decreased appropriately. She was discharged 3 days after treatment but subsequently returned with right lower quadrant pain, nausea, vomiting and fever. The patient underwent laparoscopy with removal of a suppurative appendix. A stable interstitial ectopic pregnancy was visualized and left in situ.

CONCLUSION: The discipline to consider concomitant abdominal pathology is paramount. The perceived rarity of an ectopic pregnancy and appendicitis should not obscure a thorough clinical evaluation. (J Reprod Med 2008;53:378-381)
