“…6 On ultrasound, cornual pregnancies may be seen as a gestational sac or an eccentric heterogenous mass in the cornual region. 8 An echogenic line extending into the center of the interstitial gestational sac or a thin myometrium of <5 mm surrounding the gestational sac may also be seen. 8 The majority of heterotopic pregnancies are treated surgically with both laparoscopic and abdominal approaches having been described.…”

“…About 75-80% of EPs occur in ampullary portion, 10-15% in isthmic portion, and about 5% in the fimbrial end of the Fallopian tube [19]. The tubal EP can be diagnosed by a transvaginal ultrasound scan (TVS) and implies an intact Fallopian tube with a pregnancy that is likely to be growing and visualized as an inhomogeneous mass that might well be a collapsed sac, which contains trophoblastic tissue [20].…”

An ectopic pregnancy (EP) falls within the area of the gynecological emergency and/or reproductive management of women, which is the implantation of fertilized ovum outside the endometrial cavity. The etiology of EP concentrated mainly on factor causes delayed transport of the fertilized ovum through the fallopian tube (favors implantation in tubal mucosa), thus giving rise to EP. This chapter describes the causes, diagnosis, prevention and the guidelines to improve the management of women who may have an EP, a major gynecological emergency that is a cause of morbidity or even mortality of women in first trimester. Three types of EP are diagnosed: tubal, cervical and ovarian; tubal is the main type. Identification of the signs and symptoms of acute and chronic EP in women, involving classical clinical trials or other symptoms common to early pregnancy, as well as evaluating the most important congenital and acquired factors related with EP, were discussed. Explanation of the most accurate methods used to diagnose the pregnancy including serum beta hCG and progesterone levels, medical history, ultrasonography, pregnancy tests and laparoscopy was also clarified. The evaluation of the most effective management tools of EP, including methotrexate administration and surgery (laparotomy and laparoscopy), was obviously explained.

“…Ultrasonic criteria for the diagnosis include an empty uterine cavity, a gestational sac separate from the uterine cavity, and a myometrial thinning of less than 5 mm around the gestational sac; typically the interstitial line signan echogenic line from the endometrial cavity to the corner next to the gestational mass is seen. MRI can be used particularly when it is important to distinguish between an interstitial and angular pregnancy [5].…”

Background: Interstitial pregnancy poses a great diagnostic and therapeutic challenge and carries a high maternal mortality. Because of myometrial distensibility, they tend to present late when rupture occurs. But, when diagnosed early, it can be managed conservatively.Case: A case of unruptured interstitial pregnancy diagnosed early on pelvic ultrasound, with high serum β hCG levels and managed by single dose systemic methotrexate is presented. Returning of serum β hCG to non pregnant levels and disappearance of ectopic mass occurred after 3 months of methotrexate administration. Conclusion:Early diagnosis of interstitial pregnancy could lead to successful conservative medical management and avoids the life threatening complication of rupture and surgery. In a hemodynamically stable patient of interstitial pregnancy, systemic methotrexate can be a safe option even with high β hCG concentration but long term monitoring and patience is required.
