Role of MRI in the early diagnosis of tubal ectopic pregnancy

Abstract

• MR imaging has served as a problem-solving procedure in ectopic pregnancy. • MR imaging features can be criteria for early diagnosis of tubal pregnancy. • Detailed assessment of ectopic implantation is necessary for management decision-making.

To evaluate the feasibility of magnetic resonance imaging in predicting unusual site ectopic pregnancy: a retrospective cohort study

“…In conclusion, our results show that in cases of inconclusive US, MRI can play an important role in the early diagnosis of extra-tubal pregnancy, providing accurate evaluation of the site and the possible infiltration of the lesion, which help the management of these patients [6].…”

“…EP is a well-known acute condition, and is associated with a 9-14 % mortality rate [6]. The decision to institute medical therapy versus surgery requires accurate characterization of a suspected EP.…”

“…To date we have found few observational studies [6][7][8][9][10] and several case reports [11][12][13][14][15] that focused on MRI for the diagnosis of tubal EP, without a clear assessment about its role for the unusual implantation sites.…”

MRI of Acute Gynecologic Conditions

“…Upon improper implantation of a fertilized egg in a fallopian tube, trophoblasts invade the wall of the fallopian tube to help form the placenta. This process causes hemorrhage to fill the lumen of the tube, leading to a distended tubular structure with signal characteristics of hemorrhage at various stages on MRI . In the setting of positive β‐hCG without an intrauterine gestational sac, the presence of unilateral hematosalpinx is highly concerning for an ectopic pregnancy, even without a demonstrable extrauterine gestation sac (Fig.…”

The feasibility of laparoscopically assisted, hysteroscopic removal of interstitial pregnancies: A case series

“…5,6 With the development of diagnostic methods, precise diagnosis of interstitial pregnancy before rupture has become possible, which allows gynecologists to consider more conservative treatment. 7,8 Several cases had been reported that hysteroscopic management could be a feasible option with potentially less trauma to the interstitial uterine wall and less impact on subsequent pregnancy. [9][10][11][12][13] However, most of these reports are case reports.…”
