Abstract
Intramural pregnancies (IMP) are very rare and represent about 1% of ectopic pregnancies (EPs). Despite a few reported cases, there is limited awareness & knowledge among sonographers and physicians. Moreover, no established diagnostic or treatment protocol exists for such a condition. This study identifies and synthesizes what is known about IMP, including etiology and pathophysiology, common clinical presentations, imaging features, laparoscopic and hysteroscopic findings, and management. PUBMED and Google Scholar were queried to identify eligible studies. All articles on IMP in human subjects available in English and French languages were included. Other types of ectopic pregnancies, including cesarean scar and cervical ectopic pregnancies, were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines and a narrative synthesis approach were used to systematically review the medical literature. 82 cases distributed around 27 countries with an average maternal age of 32.07 years and gestational age of 9.27 weeks were eventually selected for this study. History of curettage was the most common risk factor reported in 30 (36.58%) patients, followed by history of salpingectomy, assisted reproduction with embryo transfer, and previous cesarean delivery, in 10(12.19%), 10(12.19%), and 9(10.97%) patients respectively. Ultrasound was performed in 80(97.56%) cases. Of the 66 reported ultrasound findings, 29 were diagnostic or suggestive of IMP. MRI, laparoscopy (both diagnostic & surgical) and diagnostic hysteroscopy were carried out on 18(21.95%), 36(43.9%) and 22(26.83%) patients respectively. Histopathologic examination mainly performed after surgery was the gold standard for confirming the diagnosis. Management involved conservative (3.65%) approach, medical treatment with methotrexate or potassium chloride (23.17%), and surgical interventions. The latter includes laparoscopic surgery (25.61%), laparotomic surgery (23.17%), and hysterectomy (13.41%). IMP is a rare but potentially lethal clinical entity. A significant proportion of patients are asymptomatic and have no known risk factors. Correlation between clinical history and imaging findings is vital to establish a prompt diagnosis and reduce the risk of a catastrophic outcome.

Abstract
RATIONALE Intramural ectopic pregnancy (IMP) is a rare ectopic pregnancy with an unclear etiology, and standard treatment guidelines currently remain unclear. The main treatment option is local excision of IMP via laparoscopy or laparotomy. PATIENT CONCERNS A 32-year-old woman with adenomyosis presented with amenorrhea for 7 weeks and a serum β-human chorionic gonadotropin (HCG) level of 6882 IU/L. The patient had a history of laparotomy for adenomyosis 5 years previously. Three-dimensional ultrasonography showed a live gestational sac (GS) of 9 × 15 × 18 mm located in the left posterior wall of the uterus and a sinus tract connecting the sac and the endometrial cavity. MRI revealed the GS located in the adenomyosis and a 1.0-cm sinus tract connecting the GS and the endometrial cavity. DIAGNOSES IMP with adenomyosis. INTERVENTIONS High-intensity focused ultrasound (HIFU) treatment combined with systemic methotrexate (MTX) was performed to treat IMP, which would avoid operation and massive bleeding. OUTCOMES Serum β-HCG levels decreased to normal 4 weeks after HIFU treatment and the GS was not found on MRI after 4 months. The sinus tract was significantly shortened after the HIFU treatment. LESSONS HIFU ablation combined with systemic MTX is effective for the treatment of IMP and is favorable for maintaining fertility.

Abstract
Differentiation between intramural ectopic pregnancy and molar ectopic pregnancy is very difficult because of their exceptional rarity. Herein, we present a misdiagnosed case of intramural pregnancy and invasive trophoblastic disease on ultrasound. A 45-year-old female patient was admitted to our tertiary referral hospital due to abdominal pain and unusual ultrasonography findings. Initially, a diagnosis of intramural ectopic pregnancy was identified based on transvaginal color Doppler ultrasonography, 3-dimensional ultrasound, and serial serum beta-human chorionic gonadotropin, thus the patient underwent laparotomy with hysterectomy. However, the histopathological endpoint showed an invasive trophoblastic disease. Clinically, this pathology should be included in the differential diagnosis of intramural ectopic pregnancy since an imaging scan remains quite unclear.

Abstract
Objectives
Uterine myomas are a frequent finding in reproductive age women with an estimated incidence 12–25%. 1. Treatment of uterine myomas to facilitate good pregnancy rates and outcome, such as hysteroscopic, laparoscopic, abdominal resection uterine artery embolization among others were evaluated in terms of pregnancy outcome. While the literature is replete of the pregnancy complication of uterine rupture after myomectomies, 2–4 there are very few publications evaluate a relatively rare pregnancy complication associated with placental implantation within the uterine cavity at the site of the previous myomectomy, namely the myomectomy scar pregnancy (MSP). Despite their relative rarity, this type of pathologically adherent placenta rightfully belongs to the well-known entity of placenta accreta spectrum (PAS).
Case presentation
We present a complicated case of MSP and review the available literature to raise attention to its clinical appearance, its prenatal diagnosis so appropriate intrapartum management can be planned.
Conclusions
Despite the rarity of MSP, continuous attention should be given at every single routinely scheduled or indication driven obstetrical US scan following myomectomies to evaluate the placental site implantation regardless of the route and technique of their initial surgical procedure.

Abstract
Background: Intramural ectopic pregnancy is defined as the gestational sac (GS) is entirely within the myometrium, separate from the endometrial cavity and fallopian tubes, which is unsustainable and potentially life-threatening. The data investigating the clinical characteristics, management strategy, and fertility outcomes after treatment of intramural ectopic pregnancies are very limited due to its extreme rarity. Methods: To investigate the clinical characteristics, treatment options, and fertility outcomes in patients with intramural ectopic pregnancy, a retrospective study included 56 patients was conducted. We also used logistic regression to identify potential risk factors for uterine rupture and hysterectomy in these patients. Results: The mean age of patients was 31.1 years, with an average gestational age (GA) of 10.0 weeks, and the majority of the patient cohort (83.9%) had uterine or endometrial surgical history. 55.4% of the intramural pregnancy was diagnosed by preoperative imaging examination and 67.7% was detected by ultrasound. There was no dominant predisposed zone of the GS. Common treatment strategies included laparotomy surgery (41.1%) and laparoscopic surgery (35.7%), followed by methotrexate (7.1%) and expectant management (5.4%). Uterine rupture occurred in 9 patients and 8 patients underwent a hysterectomy, but no maternal demise was found. Logistic regression showed that a GA >10 weeks predicted a significantly higher risk of uterine rupture (Odds ratio [OR] 8.000, 95% confidence interval [CI] 1.456-43.966, P = 0.017) and hysterectomy (OR 12.333, 95% CI 2.125-71.565, P = 0.005), and GS located in the fundus also predicted higher probability of uterine rupture (OR 7.000,95% CI 1.271-38.543, P = 0.025). Among the ten patients who had a desire for fertility, 6 of them succeeded and 4 of them successfully delivered with a GA ≥ 34 weeks. Conclusion: GA > 10 weeks was the risk factor for both uterine rupture and hysterectomy, while patients with GS located in the uterine fundus had a significantly higher risk of uterine rupture. The fertility outcomes were moderate after treatment. The management strategies should be individualized according to disease conditions and the desire for fertility, and early diagnosis is essential for optimizing clinical outcomes.

Abstract
Myomectomy scar pregnancy (MSP) is a rare disease, which is defined as a gestational sac located within a previous myomectomy scar. MSP is an uncommon late complication of uterine fibroids after myomectomy. We report a case where the implantation site matched the site of the previous myomectomy, and review the existing literature. A 28-year-old pregnant woman presented with vaginal bleeding. She was diagnosed with MSP by ultrasound and magnetic resonance imaging, and then underwent laparotomic enucleation. The patient's postoperative course was uneventful. Taking into account the findings in our case and the seven other reported cases of MSP, we propose that MSP can be divided into three types and that surgical enucleation of the pregnancy mass is an effective treatment.

Abstract
Myomectomy scar pregnancy is a rare intramural pregnancy in which gestational sac is implanted in the myometrium, in the previous myomectomy scar separate from endometrial cavity and fallopian tubes. Heterotopic pregnancy is presence of simultaneous gestation at two or more implantation sites. Our patient presented at 7 weeks, in-vitro fertilization (IVF) conception with previous four IVF failures and myomectomy 3 months prior. Transvaginal sonography revealed twin live pregnancies, one intrauterine and another in the posterior wall of the uterus distinctly separate from the endometrial cavity. Laparoscopy revealed a ruptured intramural pregnancy, another unruptured tubal pregnancy which was initially missed by USG. After laparoscopic management, intrauterine pregnancy continued resulting in live birth at 35 weeks. This case adds to the literature and highlights the importance of early diagnosis and timely intervention of a rare form of an ectopic gestation. This is the only reported case in literature with a heterotopic gestation and a coexistent myomectomy scar pregnancy and the only one resulting in successful live birth after laparoscopic management of a ruptured myomectomy scar pregnancy in a heterotopic gestation. Early diagnosis is important for salvaging the intrauterine gestation and one should actively look for them at viability scan especially in assisted reproductive technology (ART) conception and scarred uterus.

Abstract
Background Intramyometrial pregnancy is a rare subtype of ectopic pregnancy. The cases following IVF-ET were few reported in recent years. The etiological factors include previous uterine trauma like myomectomy, salpingectomy, dilatation and curettage, assisted reproductive technologies and adenomyosis. Early diagnosis is difficult to make due to its various manifestation. The medical treatment includes conservative management with surgical excision, aortic balloon occlusion, uterine artery embolization, MTX etc. Sometimes hysterectomy was performed due to delayed diagnosis. Case presentation In this article, we presented a case of a 28 years old woman who had cryopreserved embryo transfer with a history of right side salpingectomy. We suspected it a right adnexa ectopic pregnancy at the first place, especially the right fallopian interstitial or right uterus cornu due to ultrasonography and medical history. The product of conception was discovered embedded in the myometrium and protruding out from the right side of the posterior uterine wall, with seemingly no connection with uterine cavity nor fallopian tubes. The diagnosis of intramural pregnancy was made intraoperatively and validated after pathological report. The interventions were made early enough that exploratory laparoscopy, hysteroscopy and conservative surgical excision were successfully performed at 7 weeks’ gestation preserving the fertility. Conclusions It is important for clinicians to be aware of risk factors of intramural pregnancy and maintain an index of suspicion in ART treatment. Ultrasound and laparoscopy are essential managements for early diagnose which make conservative treatment possible and prevent life-threatening consequences.

Abstract
BACKGROUND Intramural pregnancy is an uncommon type of ectopic pregnancy, where the gestational sac is completely encircled by myometrium and unconnected with endometrial cavity, fallopian tubes or round ligament. Owing to its potentially life-threatening hemorrhage and uterine rupture, early diagnosis and management are urgently required. We present a case of a woman undergoing zigzag medical procedures, which featured non-consensus preoperative diagnosis of intramural and interstitial pregnancy and an intramural ectopic pregnancy ultimately confirmed and successfully removed by emergency laparoscopy. Additionally, we present a review of the related literature and discuss its varied clinical features, imageological characters, diagnosis, differential diagnosis and multiple treatments. METHODS A comprehensive bibliographic search through PubMed, using keywords: intramural ectopic pregnancy. Relevant literatures published from January 2013 to April 2019 were reviewed. RESULTS Twenty-four cases in total for intramural ectopic pregnancy including this report were reviewed. Diagnoses were mainly made by ultrasound images. Most patients had a history of uterine surgery or intrauterine operation and had been surgically resected. None of the mothers were in danger, but only one case had live birth at 37 weeks of gestation. CONCLUSION Non-specific clinical presentation and non-uniform ultrasound criteria pose a challenge for us to make timely and accurate management. Integrated radiological examinations and communication and cooperation between sonographers and gynecologists play a vital role in diagnostic accuracy and selecting the optimal therapeutic method of an intramural pregnancy.
