Cornual Pregnancy

Abstract

Cornual pregnancy (CP) is a subtype of ectopic pregnancy that is implanted in the interstitial segment of the fallopian tube which is defined as the tubal section crossing uterine muscular tissue. Widely recognized risk factors for CP are endometriosis, uterine leiomyomata, or pelvic inflammatory disease; all these diseases can cause tubal anatomic changes and consequently alter embryo physiological implant process. Many treatment options are available for this condition each one must be tailored according to patient and operating scenario. The incidence of uterine ruptures in the scarred uterus appears to be low, but the fear of it remains and therefore medical treatment might be favored over cornual wedge resection. The actual risk of uterine rupture after medical treatment is unknown. Multiple testing strategies exist to diagnose CP, but caution needs to be used to avoid a false diagnosis.

Regarding Cornual Pregnancy

“…According to Gaetani et al .’s study,[ 1 ] Figure 2 shows a uterus without any Müllerian anomaly which supports our suggestion that the published article “Cornual Pregnancy” by Gaetani et al . [ 1 ] should be changed to interstitial EP (IEP).…”

“…Gaetani et al ,[ 1 ] mentioned in their published article that cornual ectopic pregnancy (EP) is a subtype of EP that occurs after the fertilized ovum’s implantation in the interstitial part of the fallopian tube (FT) where it crosses the uterine muscular tissue to enter the uterine cavity.…”

“…The published article “Cornual Pregnancy” by Gaetani et al . [ 1 ] is somewhat confusing to the readers.…”

“…According to Gaetani et al .’s study,[ 1 ] Figure 1 shows the sonographic criteria of the interstitial EP (IEP) (i.e., empty uterus with an eccentric sac. The eccentric sac is >1 cm away from the lateral endometrial margin and surrounded by <5 mm myometrium).…”

Uterine Manipulation May Not Influence Ongoing Pregnancy: Case Report and Literature Review

“…These are typically in the fallopian tube or in rarer locations such as a cornual or ovary, which accounts for 2%–4% and 0.5%–3%, respectively, of all EP. [ 5 8 9 ] A high index of clinical suspicion for EP is required, for patients who present with abdominal pain and found to have a positive urine pregnancy test (UPT) with adnexal mass or free fluid on imaging. As for cases of acute appendicitis, early diagnosis and appropriate treatment of EP is key to significantly reducing maternal morbidity and mortality as well as preserving fertility.…”
