Introduction: Prenatal diagnosis of abdominal cysts is challenging owing to the heterogeneity of these lesions. The aim of this study was to review our case series, assess the diagnostic accuracy of prenatal ultrasound, and identify predictive factors of postnatal outcome. Materials and Methods: A single-centre retrospective study conducted between 2015 and 2025. Obstetric, fetal, and ultrasonographic data were collected and correlated with diagnosis and postnatal outcome. Results Sixty-one cases were identified, 10 of which were excluded due to pregnancy termination (3) or incomplete data (7). Fifty-one neonates were included: ovarian cyst (28; 54.9%), intestinal duplication (7; 13.7%), duodenal atresia (2), hepatic cyst (2), splenic cyst (2), adrenal cyst (2), renal cyst (2), pelvic cyst (1), mesenteric cyst (1), and Meckel's diverticulum cyst (1). Spontaneous regression was observed in 3 cases (5.9%). The diagnostic accuracy of prenatal ultrasound was 66.6% (34/51; 95% CI: 53–80%). A reduction in cyst size during pregnancy was associated with greater diagnostic accuracy (p=0.0403). Eleven patients (21.6%) underwent surgery at a median age of 0.39 months. Lesion diameter at diagnosis was significantly associated with the need for surgical treatment (p=0.0418), with a higher risk for cysts ≥5 cm. A trend was also observed between earlier prenatal diagnosis and a higher frequency of surgery (p=0.0556). Conclusions: The size of an abdominal cyst during pregnancy represents the main predictive factor for surgical treatment. Furthermore, monitoring size variations may improve risk stratification and prenatal counselling.
Obiettivo: La diagnosi prenatale delle cisti addominali è complessa per l'eterogeneità delle lesioni. Scopo dello studio è revisionare la nostra casistica, valutare la capacità diagnostica dell'ecografia prenatale e identificare fattori predittivi dell'outcome postnatale. Materiali e metodi: Studio retrospettivo monocentrico condotto tra il 2015 e il 2025. Sono stati raccolti dati ostetrici, fetali ed ecografici, correlati con diagnosi e outcome postnatale. Risultati: Sono stati identificati 61 casi, di cui 10 esclusi per aborto (3) o dati incompleti (7). Sono stati inclusi 51 neonati: cisti ovarica (28; 54,9%), duplicazione intestinale (7; 13,7%), atresia duodenale (2), cisti epatica (2), splenica (2), surrenalica (2), renale (2), pelvica (1), mesenterica (1) e del diverticolo di Meckel (1). In 3 casi (5,9%) si è osservata regressione spontanea. L'accuratezza diagnostica dell'ecografia prenatale è risultata del 66,6% (34/51; IC95%: 53-80%). La riduzione delle dimensioni della cisti durante la gravidanza è risultata associata a una maggiore accuratezza diagnostica (p=0,0403). Undici pazienti (21,6%) sono stati sottoposti a chirurgia a un'età mediana di 0,39 mesi. Il diametro della lesione alla diagnosi è risultato significativamente associato alla necessità di trattamento chirurgico (p=0,0418), con rischio maggiore per cisti ≥5 cm. È stato inoltre osservato un trend tra diagnosi prenatale più precoce e maggiore frequenza di chirurgia (p=0,0556). Conclusioni: La dimensione di una cisti addominale in gravidanza rappresenta il principale fattore predittivo di trattamento chirurgico. Inoltre, il monitoraggio delle variazioni dimensionali può migliorare la stratificazione del rischio e il counselling prenatale.
