Abstract: Background: Conjoined twins are a rare phenomenon, with cranio-thoraco-omphalopagus being among the rarest forms. Early antenatal diagnosis is crucial for parental counseling and management planning. We report this case to highlight the importance of detailed ultrasound assessment in detecting such anomalies. Case Presentation: A 30-year-old primigravida of Indian ethnicity at 18 weeks of gestation was referred to our center for a second opinion following an abnormal antenatal ultrasound performed at another clinic. A detailed mid-trimester anomaly scan confirmed the presence of cranio-thoraco- omphalopagus conjoined twins, characterized by fusion at the cranium, thorax, and upper abdomen. The diagnosis was further supported by fetal echocardiography, which revealed a shared cardiac complex. After counseling, the patient and her family opted for termination of pregnancy due to the poor prognosis. Conclusions: This case underscores the significance of early and accurate prenatal ultrasound in diagnosing complex fetal anomalies. Timely detection allows for informed decision-making and appropriate perinatal management.
