Imaging of Omphalopagus: A Case Report

Omphalopagus is a form of conjoined twins with relatively good prognosis. In this rare congenital anomaly, the union of the twins starts at the lower part of the thorax and extends to the umbilical region. We relate the case of conjoined omphalopagus twins lately diagnosed by ultrasonography and foetal MRI at 28-weeks gestation. Case report: We received a 28 years-old primigravid nulliparous patient at 28-weeks gestation, diagnosed with omphalopagus conjoined twins by ultrasonography. We then proceeded with foetal MRI to further assess the health of the twins. Conclusion: Although an early diagnosis by ultrasound can be auspicious, the use of foetal MRI late in a conjoined twins pregnancy can be a great tool to help the surgical team plan their therapeutic strategy.
