Biswas S, Gomez J, Horgan R, Sibai BM, Saad A, Powel JE, Al-Kouatly HB. Mirror syndrome: a systematic literature review. Am J Obstet Gynecol MFM 2023; 5:101067. [PMID: 37385374 DOI: 10.1016/j.ajogmf.2023.101067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 06/15/2023] [Accepted: 06/22/2023] [Indexed: 07/01/2023]
Abstract
OBJECTIVE This study aimed to review the diagnostic criteria for mirror syndrome and describe its clinical presentation. DATA SOURCES Databases from PubMed, Scopus, Cochrane Library, ClinicalTrials.gov, and CINAHL were inquired for case series containing ≥2 cases of mirror syndrome from inception to February 2022. STUDY ELIGIBILITY CRITERIA Studies were included if they reported ≥2 cases of mirror syndrome and included case reports, case series, cohort studies, and case-control studies. STUDY APPRAISAL AND SYNTHESIS METHODS The studies' quality and risk of bias were independently assessed. Data were tabulated using Microsoft Excel and summarized using narrative review and descriptive statistics. This systematic review was conducted according to the Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement. All eligible references were assessed. Screening of records and data extraction were independently performed, and a third author resolved disagreements. RESULTS Of 13 citations, 12 studies (n=82) reported diagnostic criteria for mirror syndrome: maternal edema (11/12), fetal hydrops (9/12), placental edema (6/12), placentomegaly (5/12), and preeclampsia (2/12); 12 studies (n=82) described the clinical presentation of mirror syndrome as maternal edema (62.2%), hypoalbuminemia (54.9%), anemia (39.0%), and new-onset hypertension (39.0%); 4 studies (n=36) reported that hemodilution was present in all patients; 8 studies (n=36) reported the etiology of fetal hydrops, with the most common being structural cardiac malformations (19.4%), alpha thalassemia (19.4%), Rh isoimmunization (13.9%), and nonimmune hydrops fetalis (13.9%); and 6 studies (n=47) reported maternal complications, 89.4% of which were major: postpartum hemorrhage (44.7%), hemorrhage requiring blood transfusion (19.1%), intensive care unit admission (12.8%), heart failure (10.6%), pulmonary edema (8.5%), and renal dysfunction (8.5%). In 39 cases, the reported fetal outcomes were stillbirth (66.6%) and neonatal or infant death (25.6%). The overall survival rate among continued pregnancies was 7.7%. CONCLUSION The diagnostic criteria of mirror syndrome differed considerably among studies. Mirror syndrome clinical presentation overlapped with preeclampsia. Only 4 studies discussed hemodilution. Significant maternal morbidity and fetal mortality were associated with mirror syndrome. Further research is warranted to elucidate the pathogenesis of mirror syndrome to better guide clinicians in identifying and managing the condition.

Abstract
Prenatal assessment of the inferior vena cava (IVC) should be considered in pregnancies with atypical presentations of fetal ascites and placentomegaly. We examine a case of a 25-year-old gravida 2 para 1 type 1 diabetic female at 29 and 4/7 weeks' gestation. Ultrasound (US) showed fetal ascites and placentomegaly with increased middle cerebral artery peak systolic velocity (MCA-PSV) suspicious of fetal anemia. Cordocentesis with intrauterine transfusion briefly resolved the fetal ascites, though the mother developed pulmonary edema and pleural effusion, suggestive of mirror syndrome. On US, fetal ascites returned and progressed to non-immune hydrops fetalis, prompting delivery. Neonatal US revealed a heterogenous and calcified thrombus within the IVC.

Int J Womens Health 2023; 15:411-425. [PMID: 36974131 PMCID: PMC10039711 DOI: 10.2147/ijwh.s397680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Accepted: 03/13/2023] [Indexed: 03/29/2023] Open
Abstract
Background Preeclampsia is a leading cause of maternal and perinatal mortality and morbidity. The management of preeclampsia has not changed much in more than two decades, and its aetiology is still not fully understood. Case reports and case series have traditionally been used to communicate new knowledge about existing conditions. Whether this is true for preeclampsia is not known. Objective To determine whether recent case reports or case series have generated new knowledge and clinical discoveries about preeclampsia. Methods A detailed search strategy was developed in consultation with a medical librarian. Two bibliographic databases were searched through Ovid: Embase and MEDLINE. We selected case reports or case series published between 2015 and 2020, comprising pregnant persons diagnosed with hypertensive disorders of pregnancy, including preeclampsia. Two reviewers independently screened all publications. One reviewer extracted data from included studies, while another conducted a quality check of extracted data. We developed a codebook to guide our data extraction and outcomes assessment. The quality of each report was determined based on Joanna Briggs Institute (JBI) critical appraisal checklist for case reports and case series. Results We included 104 case reports and three case series, together comprising 118 pregnancies. A severe presentation or complication of preeclampsia was reported in 81% of pregnancies, and 84% had a positive maternal outcome, free of death or persistent complications. Only 8% of the case reports were deemed to be of high quality, and 53.8% of moderate quality; none of the case series were of high quality. A total of 26 of the 107 publications (24.3%) included a novel clinical discovery as a central theme. Conclusion Over two-thirds of recent case reports and case series about preeclampsia do not appear to present new knowledge or discoveries about preeclampsia, and most are of low quality.

Is Fetal Hydrops in Turner Syndrome a Risk Factor for the Development of Maternal Mirror Syndrome? J Clin Med 2022; 11:jcm11154588. [PMID: 35956203 PMCID: PMC9369874 DOI: 10.3390/jcm11154588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 07/10/2022] [Accepted: 07/30/2022] [Indexed: 11/17/2022] Open
Abstract
Mirror syndrome is a rare and serious maternal condition associated with immune and non-immune fetal hydrops after 16 weeks of gestational age. Subjacent conditions associated with fetal hydrops may carry different risks for Mirror syndrome. Fetuses with Turner syndrome are frequently found to be hydropic on ultrasound. We designed a retrospective multicenter study to evaluate the risk for Mirror syndrome among pregnancies complicated with Turner syndrome and fetal hydrops. Data were extracted from a questionnaire sent to specialists in maternal fetal medicine in Germany. Out of 758 cases, 138 fulfilled our inclusion criteria and were included in the analysis. Of the included 138, 66 presented with persisting hydrops at or after 16 weeks. The frequency of placental hydrops/placentomegaly was rather low (8.1%). Of note, no Mirror syndrome was observed in our study cohort. We propose that the risk of this pregnancy complication varies according to the subjacent cause of fetal hydrops. In Turner syndrome, the risk for Mirror syndrome is lower than that reported in the literature. Our observations are relevant for clinical management and parental counseling.

Abstract
Mirror syndrome is a rare clinical condition in pregnancy associated with significant fetal mortality and maternal morbidity. It is characterized by a triad of complications: fetal hydrops, placenta oedema, and maternal oedema. We are reporting one case of late-onset Mirror syndrome in which the patient presented later in the gestation of 36 weeks due to excessive weight gain and clinical sign mimicking preeclampsia. Awareness of this disease is essential, as a failure of recognition will delay the treatment and cause higher maternal and perinatal morbidity and mortality.

Abstract
Congenital brain tumors, defined as those diagnosed prenatally or within the first 2 months of age, represent less than 2% of pediatric brain tumors. Their location, prevalence and pathophysiology differ from those of tumors that develop later in life. Imaging plays a crucial role in diagnosis, tumor characterization and treatment planning. The most common lesions diagnosed in utero are teratomas, followed by gliomas, choroid plexus papillomas and craniopharyngiomas. In this review, we summarize the pathogenesis, diagnosis, management and prognosis of the most frequent fetal brain tumors.

Abstract
Fetal tumors represent an infrequent pathology when compared to congenital malformations, although their true incidence may be underestimated. A variety of benign and malignant neoplasms may occur anywhere in the neural axis. Imaging plays an important role in the fetal tumor diagnosis and evaluation of their resultant complications. Discovery of a fetal mass on obstetric ultrasound necessitates further evaluation with prenatal magnetic resonance imaging (MRI). New MR sequences and new applications of existing techniques have been successfully implemented in prenatal imaging. A detailed assessment may be performed using a variety of MR. Fetal tumors may be histologically benign or malignant, but their prognosis generally remains poor, especially for intracranial lesions. Unfavorable tumor location or heightened metabolic demands on a developing fetus may result in severe complications and a fatal outcome, even in cases of benign lesions. Nowadays, prenatal treatment focuses mainly on alleviation of secondary complications caused by the tumors. In this article we review congenital tumors of the brain, face, and neck encountered in prenatal life, and discuss diagnostic clues for appropriate diagnosis.
