Abstract
The ampulla portion of the fallopian tube is the most common site of ectopic pregnancy (70%), with approximately 2% of pregnancies implanted in the interstitial portion. In general, an interstitial ectopic pregnancy (IEP) is difficult to diagnose and is associated with a high rate of complications-most patients with an IEP present with severe abdominal pain and haemorrhagic shock due to an ectopic rupture. Chronic tubal pregnancy (CTP) is an uncommon condition with an incidence of 20%. The CTP has a longer clinical course and a negative or low level of serum beta-human chorionic gonadotropin due to perished chorionic villi. This study presents a case of a woman who was diagnosed with a chronic IEP (CIEP) which was successfully treated by surgery. This case also acts as a cautionary reminder of considering a CIEP in women of reproductive age presenting with amenorrhea, vaginal bleeding and a negative pregnancy test.

Abstract
Endometriosis is a chronic and disabling gynecological disease that affects women of reproductive age. Magnetic resonance imaging (MRI) is considered the cornerstone radiological technique for both the diagnosis and management of endometriosis. While MRI offers higher sensitivity compared to ultrasonography, it is prone to false-positive results, leading to decreased specificity. False-positive findings can arise from various T1-hyperintense conditions on fat-suppressed T1-weighted images, resembling endometriotic cystic lesions in different anatomical compartments. These conditions include hemorrhage, hyperproteic content, MRI artifacts, feces, or melanin. Such false positives can have significant implications for patient care, ranging from incorrect diagnoses to unnecessary medical or surgical interventions and subsequent follow-up. To address these challenges, this educational review aims to provide radiologists with comprehensive knowledge about MRI criteria, potential pitfalls, and differential diagnoses, ultimately reducing false-positive results related to T1-hyperintense abnormalities.Critical relevance statementMRI has a 10% false-positive rate, leading to misdiagnosis. T1-hyperintense lesions, observed in the three phenotypes of pelvic endometriosis, can also be seen in various other causes, mainly caused by hemorrhages, high protein concentrations, and artifacts.Key points• MRI in endometriosis has a 10% false-positive rate, leading to potential misdiagnosis.• Pelvic endometriosis lesions can exhibit T1-hyperintensity across their three phenotypes.• A definitive diagnosis of a T1-hyperintense endometriotic lesion is crucial for patient management.• Hemorrhages, high protein concentrations, lipids, and artifacts are the main sources of T1-hyperintense mimickers.

Abstract
Ectopic pregnancy accounts for 1-2% of all pregnancies. Ultrasound is the primary diagnostic tool to locate pregnancy outside the uterus and identify complications such as haemoperitoneum. In inconclusive cases, MRI is an adjunctive imaging modality offering more precise tissue differentiation and helpful to location identification. Presented is an unusual case of tubal pregnancy. The patient in her 30s, who was 14 weeks into her first pregnancy, had a suspected abdominal pregnancy. Both transabdominal ultrasound and an MRI indicated an ectopic pregnancy, likely originating from the right fallopian tube. A successful laparotomy and right salpingectomy were performed without complications. Rarely, as in this case, large unruptured and advanced tubal pregnancies can mimic an abdominal pregnancy, underscoring the importance of disease recognition and familiarity with uncommon image findings. An accurate diagnosis of pregnancy location is crucial for effective case management.

Abstract
Acute abdominopelvic pain in pregnant and postpartum patients presents clinical and therapeutic challenges, often requiring quick and accurate imaging diagnosis. Ultrasound remains the primary imaging investigation. Magnetic resonance imaging (MRI) has been shown to be a powerful diagnostic tool in the setting of acute abdominal pain during pregnancy and puerperium. MRI overcomes some drawbacks of US, avoiding the ionizing radiation exposure of a computed tomography (CT) scan. Although CT is not usually appropriate in pregnant patients, it is crucial in the emergency evaluation of postpartum complications. The aim of this article is to provide radiologists with a thorough familiarity with the common and uncommon pregnancy and puerperium abdominal emergencies by illustrating their imaging appearances. The present first section will review and discuss the imaging findings for acute abdominopelvic pain of obstetric (non-fetal) etiology.

Abstract
Introduction Currently, the treatment strategies for angular pregnancy in the first trimester after assisted reproduction technology (ART) are unclear. Improper treatment will cause unnecessary losses to patients, especially infertile patients, after ART. The purpose of this study was to clarify the pregnancy outcomes of expectant treatment for angular pregnancy post-ART and to provide a basis for the formulation of clinical treatment strategies. Method This retrospective case series study was performed at the Reproductive Medicine Center of a university hospital. Maternal data and pregnancy outcomes were collected and analyzed for all patients diagnosed with angular pregnancies after ART between January 2016 and August 2021. The outcomes included live birth, term birth, premature birth, early pregnancy loss, fetal death, placental abruption, uterine rupture, maternal death, and hysterectomy. Results A total of 78 patients were analyzed in this study, of whom 54 (69.2%) had live births, 44 (56.4%) had term births, 21 (26.9%) had an early pregnancy loss, 1 (1.3%) had mid-trimester missed abortion, 1 (1.3%) underwent mid-trimester labor induction due to fetal malformation, and 1 (1.3%) underwent uterine rupture. There were no cases of maternal death, placental abruption, or hysterectomies. Discussion Angular pregnancy after ART is not as dangerous as that described in previous studies; most cases could be treated expectantly under close-interval follow-up and obtain live birth.

Abstract
Angular pregnancy is an exceedingly rare diagnosis, with less than 100 reported cases. Angular pregnancy is important to distinguish from ectopic pregnancies due to the fact that they have the potential to be viable while true ectopic pregnancies do not. As such, angular pregnancy requires starkly different management. Inappropriate use of the terms angular, interstitial, and cornual indicates a general misunderstanding of what makes these diagnoses unique. Misunderstanding leads to misdiagnosis and consequent mismanagement. Our experience with cases of women with angular and interstitial ectopic pregnancies is instructive as it illustrates effective diagnosis and differing management of these two diagnoses. In the two angular pregnancy cases, transvaginal ultrasonography was employed to confirm the diagnosis, which showed a lack of the interstitial line sign, contiguity of the decidua and endometrium, and an endomyometrial mantle thickness between 5 and 8 mm. One patient's angular pregnancy ultimately ruptured and was successfully managed with fully robotic cornual resection and unilateral salpingectomy, while the other progressed to term normally without complication. The patient with an interstitial ectopic pregnancy was also managed surgically, although with laparoscopic cornuotomy and salpingectomy.

Abstract
PURPOSE To describe the MRI features of rudimentary horn pregnancy (RHP) with surgical correlations. METHODS Nine women with a RHP underwent preoperative pelvic MRI. MRI protocol included T2- (n = 9), T1- (n = 7), and fat-suppressed contrast-enhanced T1-weighted sequences (n = 4). Two pelvic radiologists retrospectively analyzed MR images to assess the following MRI features: presence of a myometrium around the gestational sac (GS) and characteristics of its wall, GS surrounded by myometrium in contact with the round ligament, communication of the GS with the endometrial cavity of the main horn, continuity of the GS with the cervix, fibrous or muscular GS attachment to the main horn, lateral deviation, and endometrial thickness of the main horn. Ovaries and tubes were also assessed. MRI features were correlated with surgical findings. RESULTS Seven of the nine women [29 ± 6 SD years (range 16-37 years)] underwent surgical management. The first US diagnosed RHP in only 1/9 patients. All pregnancies were diagnosed using MRI. RHP was all located in the rudimentary horn of a unicornuate uterus. All the GS was surrounded by myometrium in contact with the round ligament. None of the RHP displayed communication with the endometrial cavity of the main horn nor with the cervix. An attachment between the RHP and the main horn was seen in 3/9 patients. All the main horns were lateralized and empty. CONCLUSION MRI diagnosed RHP in all patients by identifying the GS surrounded by myometrium in contact with the round ligament and the absence of continuity between the GS and the cervix. LEVEL OF EVIDENCE IV-retrospective study.

Abstract
Acute uterine emergencies constitute both obstetric and gynecologic conditions. The superior image resolution, superior soft-tissue characterization, and lack of ionizing radiation make magnetic resonance imaging (MRI) preferable over ultrasonography (USG) and computed tomography (CT) in investigating uterine emergencies. Although USG is the first-line imaging modality and is easily accessible, it has limitations. USG is an operator dependent and limited by patient factors such as obesity and muscle atrophy. CT is limited by its risk of teratogenicity in pregnant females, poor tissue differentiation, and radiation effect. The non-specific findings on CT may lead to misinterpretation of the pathology. MRI overcomes all these limitations and is emerging as the most crucial imaging modality in the emergency room (ER). The evolving 3D MR sequences further reduce the acquisition times, expanding its ER role. Although MRI is not the first-line imaging modality, it is a problem-solving tool when the ultrasound and CT are inconclusive. This pictorial review discusses the various MRI techniques used in uterine imaging and the appearances of distinct etiologies of uterine emergencies across different MRI sequences.

Abstract
Various ectopic lesions occur in the abdomen and pelvis and affect multiple organs including liver, gallbladder, pancreas, spleen, and organs of the genitourinary system. Ectopic organs may be present outside their normal positions, or ectopic tissues may develop while the original organ exists in its normal position. Both benign and malignant lesions can occur in ectopic organs and tissues. Owing to their unusual location, they can often be misdiagnosed as other lesions or even malignant lesions, such as metastasis or seeding. This multimodality pictorial review provides various cases of ectopic lesions in the abdomen and pelvis, which will help narrow the differential diagnosis and guide clinical decision-making.

Abstract
Background In clinical practice it is an ongoing challenge to distinguish between angular pregnancy and interstitial pregnancy. With the three-dimensional (3D) magnetic resonance imaging (MRI) being increasingly used, it is worth exploring its role in differentiating angular pregnancy from interstitial pregnancy. This study aims to investigate how 3D MRI can help reveal the differences between these two special pregnancies in the early diagnosis. Methods We reviewed and analyzed the 3D MRI images of 50 patients with interstitial pregnancy and 55 patients with angular pregnancy retrospectively. Imaging features were identified to compare these two special pregnancies, and the ROC (Receiver Operating Characteristic) analysis was conducted to assess the diagnostic performance. Results The significant differences of the 3D MRI imaging features between interstitial pregnancy and angular pregnancy were found in the outline of uterus cavity (p < 0.001), involvement of junctional zone (p < 0.001), the signal of surroundings (p = 0.005), the relationship with round ligament (p = 0.042), and the overlying myometrial thickness (p = 0.041). Furthermore, the multivariate logistic regression analysis identified a series of significant indicators for angular pregnancy, including the junctional zone involvement, being-surrounded by hyper/iso-intensity on 3D images, and the asymmetric outline of uterus cavity. Combining these three imaging features, the AUC (Area under the Curve) of ROC curve was 0.87 in distinguishing interstitial pregnancy from angular pregnancy. Conclusions This study suggests that 3D MRI can help distinguish angular pregnancy from interstitial pregnancy in clinical practice, with the advantages that conventional MRI or ultrasound does not have. Through the significant image features, 3D MRI plays an important role in improving the timing of diagnosis, avoiding unnecessary interventions, and preventing hemorrhage in clinical practice.

Abstract
Background Angular pregnancy is a rare form of eccentric intrauterine gestation. To determine the management strategy, angular pregnancy should be differentiated from interstitial pregnancy and cornual pregnancy. Case A 37-year-old woman (gravida 5, para 4) with no previous disease history was referred because of a retained placenta with hemorrhage 20 days following the manual vacuum aspiration of an intrauterine pregnancy performed after the diagnosis of miscarriage at 8 weeks of gestation. At the initial examination, a prominent vascular mass was identified in the left lateral portion of the uterus. The patient's serum β-human chorionic gonadotropin level was 1949 IU/L. Magnetic resonance imaging revealed an enlarged angular space occupied by a suspected retained placenta with expansion of the surrounding myometrium. Three-dimensional computerized tomography showed a prominent vascular mass with a feeding left uterine artery and draining thick left ovarian vein. The diagnosis consisted of retained placenta accreta with marked vascularity after evacuation of a miscarriage in a woman with angular pregnancy. Uterine artery chemoembolization was performed followed by the administration of a single dose of systemic methotrexate. Because the gestational mass persisted and spontaneous expulsion appeared to be unlikely, despite the gradual decline of serum β-human chorionic gonadotropin levels, hysteroscopic resection of the retained placenta was performed and the patient's subsequent recovery was uneventful. Angular pregnancy is a rare form of eccentric intrauterine gestation. Angular pregnancy should be differentiated from interstitial and cornual pregnancy. Retained placenta accreta in angular pregnancy was managed by uterine artery chemoembolization and hysteroscopic resection.

Abstract
Ectopic pregnancy (EP) is a term used to describe any pregnancy which does not implant into the uterine cavity. There are several types of EPs: tubal, interstitial, ovarian, abdominal, heterotopic, cervical, and cesarean scar. Ectopic pregnancies can acutely rupture and are the number one cause of maternal death in the first trimester of pregnancy. Therefore, prompt recognition and accurate localization have significant clinical implications on patient outcome. Unfortunately, EPs have many mimickers, which can make the diagnosis challenging in certain cases. In this review, we aim to describe and illustrate sonographic findings of each type of EP, as well as present mimickers and various imaging pitfalls. We will clarify how to avoid potential misdiagnoses that could adversely affect patient outcomes. Lastly, we will briefly address management of each type of EP and discuss potential complications.

Abstract
ABSTRACT Ectopic pregnancy (EP) is a known cause of maternal mortality and may be misdiagnosed in up to 50% of pregnant female individuals (Ann Emerg Med. 1996;28(1):10-17). Magnetic resonance imaging, with its superior soft tissue resolution, is a valuable alternative diagnostic modality to diagnose EP when transvaginal ultrasound results are inconclusive. Although an extrauterine gestational sac is the most specific finding, there are other key MRI findings that can aid in diagnosing EP. As availability of MRI access in the emergency department setting increases across the nation, its utility in women with a positive pregnancy test has also increased. Specific MRI findings that are diagnostic of EP include absence of intrauterine pregnancy, adnexal mass separate from the ovary, and hemoperitoneum. In addition, intrauterine ectopic locations, especially intramural, cornual, and cervical pregnancies, can be diagnosed with increased accuracy with the help of MRI. Magnetic resonance imaging is also useful in excluding potential mimics of EP, including adnexal cysts, ovarian neoplasms, and fibroids. In summary, providing an accurate diagnosis and determining the precise location of an EP, which is supported by the use of MRI, is imperative for guiding a patient's treatment to prevent a potentially fatal outcome.

Abstract
Tumors of the genital system are common and imaging is of crucial importance for their detection and diagnosis. Several non-neoplastic diseases may mimic these tumors and differential diagnosis may be difficult in certain cases. Misdiagnosing non-neoplastic diseases as tumor may prompt unnecessary medical treatment or surgical interventions. In this article, we aimed to present the imaging characteristics of non-neoplastic diseases of the male and female genital systems that may mimic neoplastic processes. Increasing awareness of the imaging specialists to these entities may have a severe positive impact on the management of these patients.

Abstract
Ectopic pregnancy is a major cause of 1st trimester pregnancy deaths. It occurs in various locations in the abdominopelvic cavity. Ultrasonography is a first-line, rapid, and noninvasive modality for ectopic pregnancy evaluation. MRI can help clarify equivocal cases. When in doubt about the location, one should give an intrauterine pregnancy the benefit of the doubt with close ultrasound and hCG follow-up. Here, we will review the imaging findings and mimickers of ectopic pregnancies.

Abstract
AIM To investigate whether contrast-enhanced (CE)-magnetic resonance imaging (MRI) improves identification of implantation site of ectopic pregnancy. MATERIALS AND METHODS This retrospective study enrolled 63 patients in whom implantation sites had been confirmed at histopathology. Two expert radiologists for gynaecological imaging and two inexpert radiologists independently reviewed non-CE MRI and a combination of non-CE and CE-MRI (non-CE+CE-MRI), then determined implantation site with a confidence level. The following MRI features were also evaluated: extrauterine gestational sac (GS)-like structure (shape, signal intensities at T1-weighted imaging [WI], T2WI, and diffusion-weighted imaging [DWI], presence of the three rings appearance, and distinct low intensity areas at T2WI, presence of tree or dot-like components, degree of contrast enhancement), fallopian tube (dilatation, dilatation with haematoma, degree of contrast enhancement, enhanced components within the tube), and ascites. These findings were compared for non-CE and non-CE+CE-MRI data, and for expert and inexpert groups. RESULTS The expert group identified implantation sites correctly in 58/63 (92%) cases for non-CE and non-CE+CE-MRI. In the inexpert group, the correct identification was improved from 54/63 (86%) using non-CE MRI to 58/63 (92%) using non-CE+CE-MRI, but was not significant (p=0.29). In comparison between non-CE and non-CE+CE-MRI, dilation of the fallopian tubes was observed more frequently (p=0.004) and the confidence level was elevated significantly in the non-CE+CE-MRI (p<0.0001) in the inexpert group. Intergroup comparison revealed that confidence level was significantly higher in the expert group than in the inexpert group using non-CE MRI (p<0.0001), although the difference was not significant at non-CE+CE MRI (p=0.49). CONCLUSION CE-MRI did not significantly improve correct identification of ectopic pregnancy implantation sites, although the addition of contrast enhancement did enable inexpert radiologists to diagnose confidently.

Abstract
Acute gynaecologic disorders are commonly encountered in daily clinical practice of emergency departments (ED) and predominantly occur in reproductive-age women. Since clinical presentation may be nonspecific and physical findings are often inconclusive, imaging is required for a timely and accurate diagnosis. Although ultrasound is the ideal non-invasive first-line technique, nowadays multidetector computed tomography (CT) is extensively used in the ED, particularly when a non-gynaecologic disorder is suspected and differential diagnosis from gastrointestinal and urologic diseases is needed. As a result, CT often provides the first diagnosis of female genital emergencies. If clinical conditions and scanner availability permit, magnetic resonance imaging (MRI) is superior to CT for further characterisation of gynaecologic abnormalities, due to the excellent soft-tissue contrast, intrinsic multiplanar capabilities and lack of ionising radiation. The purpose of this pictorial review is to provide radiologists with a thorough familiarity with gynaecologic emergencies by illustrating their cross-sectional imaging appearances. The present first section will review the CT and MRI findings of corpus luteum and haemorrhagic ovarian cysts, gynaecologic haemoperitoneum (from either ruptured corpus luteum or ectopic pregnancy) and adnexal torsion, with an emphasis on differential diagnosis. Additionally, comprehensive and time-efficient MRI acquisition protocols are provided.

Abstract
Although usually not a first-line imaging modality in the setting of acute pelvic pain, magnetic resonance imaging (MRI) is able to depict and characterize a wide range gynecologic diagnoses with high accuracy. Lack of ionizing radiation renders MRI particularly useful for assessment of pregnant women and children. Furthermore, inherent high soft-tissue resolution of MRI allows accurate diagnosis without intravenous contrast use, which is advantageous for patients with renal insufficiency and pregnant patients. Familiarity with the typical MRI appearance of various acute gynecologic conditions helps establish the correct diagnosis. This article reviews the common MRI findings of acute gynecologic processes, in both pregnant and nonpregnant patients. Level of Evidence: 3 Technical Efficacy Stage: 3 J. Magn. Reson.

Abstract
Ectopic pregnancy is defined as a pregnancy that occurs outside of the uterine cavity (ACOG Committee on Practice Bulletins, 2018 [1]). Ectopic pregnancy is occasionally diagnosed with MRI. Particularly, when ultrasound is nondiagnostic, it is essential that radiologists are able to recognize findings of ectopic pregnancy on MRI in the emergent setting. This novel case report demonstrates specific MR imaging signs recently proposed in the literature to help identify a tubal gestational sac, the most common type of ectopic pregnancy, and is the first reported case demonstrating intraoperative correlation with MRI findings of tubal ectopic pregnancy.

Abstract
Twin tubal ectopic pregnancies are rare events but critical diagnoses to make in emergency settings. They are common in patients who received in vitro- fertilization and in those with history of PID. Unless 2 embryos are live with detectable heart beats, ultrasound cannot definitely diagnose twin tubal EP. In clinically stable patients, MRI may provide other concrete findings to establish the diagnosis and lead to better management. In literature, to best of our knowledge, there has been no reported case of twin tubal EP evaluated with MRI. In this article, we have briefly reviewed the role of MRI in different types of EP and its limitations. We report an interesting case of ruptured tubal twin EP diagnosed with MRI which was sub optimally evaluated with ultrasound.

Abstract
Background In the literature, the terms "angular", "interstitial" and "cornual" have often been inappropriately interchanged. The consequence is under-recognition of their differences as well as inaccurate imaging guidelines which do not reliably distinguish them as distinct entities. Angular pregnancies should be considered viable and may be managed to term. Case A woman at 7w5d was transferred for surgical management of a presumed interstitial ectopic pregnancy. Sonography and MRI confirmed an eccentric fundal pregnancy with a thin myometrial mantle of 2-5 mm; the diagnosis of interstitial pregnancy was favored. Upon laparoscopy, the round ligament was displaced lateral to the pregnancy bulge and the diagnosis of angular pregnancy was thus apparent. The pregnancy was continued to term and delivered via repeat cesarean section without incident. Conclusion Angular and interstitial pregnancies are different entities which cannot always be reliably distinguished via imaging alone. Diagnostic laparoscopy may be a final step in determining pregnancy location. Angular pregnancies should be considered potentially viable and may be managed to term.

Abstract
OBJECTIVE To evaluate the accuracy of pelvic MRI in the diagnosis of unusual ectopic pregnancy (EP), when ultrasound (US) examination is inconclusive. METHODS We retrospectively reviewed the medical records of 150 patients with suspected EP. Clinical, US and MRI features of 15 unusual EPs were analysed. Two radiologists independently reviewed each case resolving by consensus any diagnostic discrepancy. Interobserver agreement was assessed using the Cohen κ test. RESULTS MRI displayed a gestational sac-like structure surrounded by a thick wall in all cases. The thick wall displayed hyperintensity in 41 %, isointensity in 35 % and hypointensity in 24 % of cases on T1-weighted images. Diffusion- and fat saturation T1-weighted images were the most accurate sequences, as they enabled identification of 15/15 and 14/15 patients, respectively. Although US was false negative in detecting cervical and uterine infiltration underlying the caesarean scar, MRI was able to identify the invasion. Interobserver agreement was very good for all sequences (κ=0.892-1.0). CONCLUSIONS MRI plays an important role in the early diagnosis of unusual EP. It should be considered after negative US findings, providing accurate evaluation of the site and the possible infiltration of these lesions, which help in the management of these patients. KEY POINTS • MRI is being increasingly used as a problem-solving modality in ectopic pregnancy. • MRI plays an important role in early diagnosis of unusual ectopic pregnancy. • Knowledge of MRI features in EP is essential to determinate appropriate management.

Abstract
Background To evaluate the performance of computed tomography (CT) as a diagnostic aid to differentiate between ruptured ovarian corpus luteal cyst (ROCLC) and ruptured ectopic pregnancy with hemorrhage (REPWH). Methods A total of 36 patients treated at our hospitals for ROCLC and REPWH from June 2014 to August 2017 were included in this study. Based on the diagnosis, the study population was divided into ROCLC group (n = 21) and REPWH group (n = 15). CT scans were performed for all patients prior to treatment. The size of the cystic shadows and the depth of the pelvic effusion were analyzed and compared with independent sample Student’s t test and Fisher’s exact test. Results Cystic shadows with maximum diameters ≥3.0 cm presented in 16 patients with ROCLC and 1 patient with REPWH, while 4 patients with ROCLC and 9 patients with REPWH exhibited cystic shadows with maximum diameters <3.0 cm. The mean diameters along the major and minor axes in the two groups were 3.76 ± 1.11 cm and 2.93 ± 0.98 cm, 1.96 ± 0.65 cm and 1.60 ± 0.55 cm, respectively (p < 0.001). The mean depth of the pelvic effusion in patients with ROCLC and REPWH were 5.20 ± 2.47 cm and 6.96 ± 2.07 cm, respectively (p = 0.038). Conclusion The cystic shadow of ROCLC is larger than that of the REPWH. The depth of the pelvic effusion of REPWH is deeper than that of the ROCLC. CT can help differentiate between ROCLC and REPWH based on the size of the cystic shadow and the depth of pelvic effusion in the adnexal area.

Abstract
OBJECTIVE To demonstrate the diffusion-weighted imaging (DWI) findings of ectopic pregnancy (EP) and introduce the "ring of restriction" sign by discussing possible causes. METHODS Between January 2014 and January 2017, patients with EP and examined by MRI on a 3T scanner were retrospectively evaluated. MRI and DWI findings were recorded. RESULTS A total of 40 patients were diagnosed with EP at our university hospital, 8 of whom (20%) were evaluated by MRI and DWI. All of them were haemodynamically and clinically stable and could be imaged adequately. Locations were ovary (n = 3, 37.5%), tuba (n = 2, 25%), Caesarean section scar (n = 2, 25%) and parauterine (n = 1, 12.5%). In all eight EPs, the gestational sac diameter was compatible with 7-9 weeks. With DWI, the gestational sac was seen as a thick-walled cyst-like structure. The thick wall showed diffusion restrictions in all patients (ring of restriction sign). CONCLUSIONS DWI through its cellular and molecular evidence may contribute diagnosis of EP. Advances in knowledge: Being aware of the EP wall shows diffusion restriction (ring of restriction) avoids interpretation errors especially in appropriate clinical setting with no need for contrast material.

Abstract
Recent rapid advances in assisted reproduction (ART) have led to global increase in usage of in vitro fertilization. This in turn has resulted in clinicians and imaging specialists encountering increase in complications associated with ART. The specialists dealing with infertility should be aware of potential complications associated with ART. Early diagnosis of these problems is based on clinician's suspicion and radiologist's awareness of these complications. Many of these conditions may be life threatening. Hence, early diagnosis and treatment of these complications can safeguard the fetal and maternal health.

Abstract
PURPOSE To determine if and when fetal structures are identifiable during first trimester pregnancy on magnetic resonance imaging (MRI) in women with acute abdominopelvic pain. METHODS Sixty-four first trimester MRI examinations performed for evaluation of abdominopelvic pain were reviewed retrospectively. T2-weighted images were assessed independently by three radiologists for the presence of gestational sac, yolk sac, fetal pole, and limb buds. Mean sac diameter and sac volume were determined, and logistic regression analyses were performed. Criterion values for fetal structures and gestational sac size were calculated using receiver operating characteristic analysis. RESULTS A gestational sac is present in all but two cases. The yolk sac is never identified. A fetal pole is identified at a gestational age (GA), mean sac diameter (MSD), and gestational sac volume (GSV) of greater than 6.4 weeks, 1.7 cm, and 8.9 mL, respectively. Limb buds are identified at a GA, MSD, and GSV of greater than 8.1 weeks, 3.4 cm, and 27.1 mL, respectively. There is a significant correlation between GA and gestational sac size, including the MSD (r 2 = 0.85, P < 0.01) and GSV (r 2 = 0.86, P < 0.01). CONCLUSIONS The gestational sac is readily demonstrated on T2-weighted images, but the yolk sac is not identified on routine MRI. The fetal pole and limb buds are seen on MRI at a similar GA and MSD as with published values using transvaginal sonography.

Abstract
BACKGROUND/AIMS Laparoscopy is an established, safe, and feasible management option for tubal pregnancies, even in women with significant hemoperitoneum. In case of interstitial pregnancy, however, a laparoscopic surgical approach is still a matter of debate. The objective of this study is to evaluate the safety and feasibility of a laparoscopic approach to interstitial pregnancies. METHODS A total of 92 women with ectopic pregnancy who underwent a surgical management from April 2009 to August 2015 were reviewed. Clinical and surgical outcomes of confirmed interstitial pregnancies (n = 10) (IP group) were compared with those of "more distal" tubal pregnancies (n = 79) (TP group). RESULTS Although there were no differences between the two groups in gestational age, ß-hCG values were significantly higher in the IP group (p = 0.005). All patients with IP were treated by laparoscopic wedge resection. The rate of surgical complications (p = 0.413) and subsequent MTX treatment (p = 0.531) were not significantly different between groups. Operating room (OR) time (p = 0.007) was higher in the IP than in the TP group. After stratification for the presence of hemoperitoneum this difference remained, with patients in the IP group having longer OR time (p = 0.034) and additionally higher intra-operative blood loss (EBL) (p = 0.013). On the other hand, in the absence of hemoperitoneum no differences between the two groups were observed. CONCLUSIONS In experienced hands, the laparoscopic management of interstitial pregnancies seems to be as safe and feasible as that of other tubal pregnancies. However, it could be technically more challenging, especially in case of hemoperitoneum.

Abstract
OBJECTIVE We illustrate the magnetic resonance imaging (MRI) features of non-neoplastic tubaric conditions. BACKGROUND A variety of pathologic non-neoplastic conditions may affect the fallopian tubes. Knowledge of their imaging appearance is important for correct diagnosis. With recent advances in MRI, along with conventional MR sequences, diffusion-weighted imaging (DWI) sequences are available and may improve lesion characterization by discriminating the nature of the content of the dilated tube. Tubal fluid with low signal intensity on T1-weighted images, high signal intensity on T2-weighted images and no restricted diffusion on DWI is indicative of hydrosalpinx. Content with high signal intensity on T1-weighted images and restricted diffusion on DWI is suggestive of hematosalpinx associated with endometriosis or tubal pregnancy. A dilated tube with variable or heterogeneous signal intensity content on conventional MR sequences and restricted diffusion on DWI may suggest a pyosalpinx or tubo-ovarian abscess. We describe morphological characteristics, MR signal intensity features, enhancement behaviour and possible differential diagnosis of each lesion. CONCLUSION MRI is the method of choice to study adnexal pelvic masses. Qualitative and quantitative functional imaging with DWI can be of help in characterization of tubaric diseases, provided that findings are interpreted in conjunction with those obtained with conventional MRI sequences. TEACHING POINTS • Nondilated fallopian tubes are not usually seen on MR images. • MRI is the method of choice to characterize and localize utero-adnexal masses. • MRI allows characterization of lesions through evaluation of the fluid content's signal intensity. • DWI in conjunction with conventional MRI sequences may improve tissue characterization. • Pelvic inflammatory disease is the most common tubal pathology.
