Background: Gestational trophoblastic diseases comprise the hydatiform moles (HMs), complete or partial, an abnormal development of trophoblastic tissue. HMs derive from a gametogenesis error during conception leading to an anomalous chromosomal asset. In the complete hydatiform mole (CHM), when one or two spermatozoa enter an empty oocyte, the karyotype, paternally derived, is diploid 46,XX or 46,XY. CHM is characterized by massive hydropic degeneration of the villi, with no fetal structures, easily detected by ultrasound (US) in early gestation, confirmed by elevated maternal beta-hCG levels. CHM with coexistent fetus (CHMCF) is an exceptional event with a high risk of malignant progression, and severe complications such as massive vaginal bleeding, preeclampsia, and fetal death. Methods/Results: We present a case of CHMCF in a 29-year-old woman, which resulted in a liveborn and healthy baby at 38 weeks of gestation. The patient was prenatally carefully monitored with biweekly US and periodic beta-hCG levels. Post-partum follow-up consisted of transvaginal US and beta-hCG levels at 1, 3, and 6 months. After 1 year post-delivery, both the mother and the newborn were healthy. Conclusions: CHMCF management can be challenging as shared guidelines are currently lacking and the case described may be helpful in adding more data.

Conventional radiography is widely used for postmortem foetal imaging, but its role in diagnosing congenital anomalies is debated. This study aimed to assess the effectiveness of X-rays in detecting skeletal abnormalities and guiding genetic analysis and counselling. This is a retrospective analysis of all post-abortion diagnostic imaging studies conducted at a centre serving a population of over 300,000 inhabitants from 2008 to 2023. The data were analysed using descriptive statistics. X-rays of 81 aborted foetuses (total of 308 projections; mean: 3.8 projections/examination; SD: 1.79) were included. We detected 137 skeletal anomalies. In seven cases (12.7%), skeletal anomalies identified through radiology were missed by prenatal sonography. The autopsy confirmed radiological data in all cases except for two radiological false positives. Additionally, radiology failed to identify a case of syndactyly, which was revealed by anatomopathology. X-ray is crucial for accurately classifying skeletal abnormalities, determining the causes of spontaneous abortion, and guiding the request for genetic counselling. Formal training for both technicians and radiologists, as well as multidisciplinary teamwork, is necessary to perform X-ray examinations on aborted foetuses and interpret the results effectively.
