Diprosopus or craniofacial duplications are the rarest forms of conjoined twins. The reported incidence in various literature is 1,80,000 to 15 million births (0.4% of conjoined twins. 1 Due to the rarity of the condition, the exact pathogenesis and genetics behind are yet to be unwound. In this article, we have attempted to understand the anatomical delineations better using fetal magnetic resonance imaging (MRI) and postnatal computed tomography (CT) with three-dimensional (3D) reconstructions.
case descriptionA 26-year-old primi came to us for a targeted imaging for fetal anomalies (TIFFA) scan. She was married for 7 years and was diagnosed to have primary infertility. The couple decided to proceed with the artificial reproduction technique (ART) and underwent intracytoplasmic sperm injection (ICSI) with transfer of three embryos. The nuchal translucency (NT) and the first anomaly scans were done elsewhere. NT scan done at 12 2/7 weeks gestation revealed a large
