Fetal Abdominal Cysts: Prenatal Diagnosis and Management
Gynecology & Obstetrics, 2015
Objective: Fetal intra-abdominal cystic masses are quite rare entities and their differential diagnosis is particularly perplexing. These masses encompass many different pathological cysts originating from almost every organ in the abdomen. In female fetuses, ovarian cysts are the primary cause. In our study, we investigated the techniques used in diagnosis, accuracy of methods and management strategies, and tried to summarize postnatal outcomes. Materials and methods: A total of 29 cases were evaluated retrospectively by reviewing their ultrasonography (USG) results, magnetic resonance imaging (MRI) scans, interventions in perinatal period, postnatal follow up and surgical outcomes. Results: Twenty nine (25 female 4 male) cases were included in the study. Mean gestational week at diagnosis was 30,0 ± 6,4 for ovarian cysts and 24,7 ± 7,5 for non-ovarian cysts. Mean diameter of cysts was 41,7 ± 25,4 mm. 17 cysts (56%) were of ovarian origin, 6 (20,7%) were mesenteric cysts, 3 of them (10.3%) originated from kidneys and 3 (10.3%) of the cysts turned out to be choledochal-subhepatic cysts. In postnatal period, 8 cases required surgery which was ovarian and mesenteric cysts. In two incidences, gonads had to be removed. In differential diagnosis of masses, diagnostic accuracy of USG was calculated as 72,4% while that of MRI was 87.5%. Conclusion: Fetal abdominal cysts are seen more frequently in female fetuses and recognized relatively later during the pregnancy. Aspiration of the cysts in masses with larger diameters may be useful in reducing frequency of complications leading to gonad losses. Most common non-ovarian cysts are mesenteric cysts which also cause complications and require surgical interventions. Both USG and MRI are highly accurate imaging techniques in cases with adnexial masses. They have roughly the same accuracy in differential diagnosis of fetal abdominal cystic lesions.

Fetal abdominal cysts: antenatal course and postnatal outcomes
Journal of Perinatal Medicine, 2019
Background There is little information on which to base the prognostic counselling as to whether an antenatally diagnosed fetal abdominal cyst will grow or shrink, or need surgery. This study aims to provide contemporary data on prenatally diagnosed fetal abdominal cysts in relation to their course and postnatal outcomes. Methods Fetal abdominal cysts diagnosed over 11 years in a single centre were identified. The gestational age at diagnosis and cyst characteristics at each examination were recorded (size, location, echogenity, septation and vascularity) and follow-up data from postnatal visits were collected. Results Eighty abdominal cysts were identified antenatally at 28+4 weeks (range 11+0–38+3). Most (87%) were isolated and the majority were pelvic (52%), simple (87.5%) and avascular (100%). Antenatally, 29% resolved spontaneously; 29% reduced in size; 9% were stable and 33% increased in size. Forty-one percent of cysts under 20 mm diameter increased in size, while only 20% of...

The finding of a fetal intra-abdominal cyst is relatively common and it can be due to a wide variety of clinical conditions. The aims of this study were to determine the accuracy of the prenatal ultrasound (US) in identifying the etiology of fetal intra-abdominal cysts and to describe the neonatal outcomes. All cases of fetal intra-abdominal cystic lesion referred to our center between 2004 and 2012 were reviewed. Cysts of urinary system origin were excluded. Prenatal and postnatal data were collected. Our cohort was divided into subgroups according to the prenatal suspected origin of the lesion (ovarian, mesenteric, gastro-intestinal and other locations). For each subgroup, sensitivity, specificity, positive predictive value, false-positive rate and accuracy of fetal US were calculated. 47 fetuses (10/37 M/F) were identified. The mean gestational age at the time of diagnosis was 33±4.9 weeks. Our cohort comprised 25 ovarian cysts (10 simplex and 15 complex), 3 GI duplication, 6 mes...

The aim of this study was to establish the post-natal diagnosis and outcome of antenatally diagnosed intra-abdominal cysts between 1991 and 2013 at our institution. All antenatally diagnosed intra-abdominal cysts between 1991 and 2013 were identified using a foetal anomaly database. The cysts were monitored for resolution. In all cases where the cyst had not resolved antenatally, additional post-natal scans were conducted. Antenatal diagnosis, post-natal diagnosis and outcomes were also recorded. 118 cases of antenatal intra-abdominal cysts were identified over the 22-year study period with a 98 % live birth rate. The overall accuracy of an antenatal diagnosis at our institution was 92 %. 26 cases (22 %) resolved spontaneously in utero, the majority of which (77 %) were ovarian in nature. Four tumour cases were identified in the series, which included two neuroblastomas, one yolk sac tumour and one teratoma. 90 cysts persisted post-natally with 52 % requiring surgery. These primaril...
Fetal abdominal cysts in the first trimester: prenatal detection and clinical significance
Fetal abdominal cysts in the first trimester: prenatal detection and clinical significance, 2008
Objective In order to determine the clinical significance of fetal abdominal cysts detected in the first trimester, we reviewed our experience with such cases collected over a 5-year period. Methods Five cases in which a fetal abdominal cyst was detected by ultrasound in the first trimester were identified. Information on the ultrasound findings, antenatal course and perinatal outcome was obtained in all cases.
First trimester lower abdominal cysts as early predictor of anorectal malformations
Journal of Ultrasound
Introduction Prenatal ultrasound diagnosis of anorectal malformations (ARMs) is challenging and often missed as direct visualization of the anal sphincter is not routinely performed, plus the technique is operator-dependent and inaccurate, also in expert hands. Other indirect signs, such as rectosigmoid overdistension or intraluminal calcifications, are occasionally present in late pregnancy. The detection of a cyst of the lower abdomen in the first trimester may be an early sign of ARM. Here we reported our experience and a review of the literature of such cases. Material and methods Isolated cases of lower abdomen cysts encountered in the first trimester at the Prenatal Diagnosis Unit during the last 5 years were retrieved and compared with those found in literature. Post-natal clinical data were analyzed to check the presence and type of malformations. Results A total of three cases of lower abdomen cysts were found in our center and 13 in literature. In our case series all the c...

CASE REPORT: CONGENITAL OVARIAN CYST SURGICALLY APPROACHED IN THE NEONATAL PERIOD WITH FAVORABLE EVOLUTION (Atena Editora), 2022
Introduction: Fetal ovarian cysts are the second most common type of abdominal mass, after the urinary tract mass. In most cases, they are small, unilateral, benign, asymptomatic, diagnosed in the third trimester and regress spontaneously. Case report: A.G.B, born weighing 4280g, daughter of a morbidly obese and chronically hypertensive mother, with an ultrasound diagnosis of a maternal cyst during pregnancy. After birth, significant abdominal distension was observed, with visceromegaly and hepatosplenomegaly, with collateral circulation and congestion. During preoperative examinations, distention of the intestinal loops to the left and a voluminous intra-abdominal cystic image were observed, which had a mass effect, displacing adjacent structures, without exact location. At 6 days of age, she underwent oophoroplasty, which showed the presence of a congenital ovarian cyst, and the cyst was evacuated and removed, measuring 13.0x11.5x4.0 cm, and anatomopathological evidence showing the benignity of the condition. Discussion: Pregnancy presented several maternal risk factors for the presence of congenital ovarian cysts that, although they regress spontaneously during pregnancy or in the first months, surgical approach was necessary due to the mass effect exerted, with possible ovarian preservation. The importance of early recognition of this possible diagnosis as well as the possible consequences is highlighted.
