RESUMEN
Diprosopus is one of the rarest types of conjoined twins, caused by incomplete zygote separation in early pregnancy. It defines a condition with duplication of facial structures, monocephalic and 1 trunk. Early detection is difficult, but fetal MRI plays an important role in strengthening antenatal diagnosis of conjoined twin pregnancies and other major congenital abnormalities, complementing antenatal ultrasonography. A 28-year-old patient (G2P1A0) was referred from the regional general hospital for suspected malformations, including Dandy-Walker syndrome and a small mandible Antenatal 3-D ultrasound at 35 weeks revealed a single baby with macrosomia, hypoplasia of the vermis, and cleft lip with malformation of facial structures. A 3 Tesla MRI (Signa, GE Healthcare) revealed various developmental brain anomalies, including duplication of the frontotemporal lobes, corpus callosum agenesis, and small posterior fossa. The identification of 4 orbital structures raised suspicions of face duplication. This patient underwent a caesarean section and delivered a diprosopus twin baby. MRI emerged as an indispensable adjunct, complementing ultrasound in detecting congenital malformations. The success of this approach emphasizes collaborative efforts between clinicians and radiologists for accurate identification and management of complex fetal anomalies.
RESUMEN
Caudal regression syndrome (CRS) is a rare inherited disorder associated with orthopedic deformities, as well as urological, anorectal, and spine malformations. We present 3 cases of CRS found in our hospital, along with the respective radiologic and clinical findings of the disease. With different problems and chief complaints from each case, we propose a diagnostic algorithm that can be used as a helpful tool in managing CRS. CRS is a complex and rare congenital disorder that affects multiple systems and can result in a range of malformations. The diagnostic algorithm proposed from our findings from 3 CRS cases is important to help healthcare providers identify the types of CRS and apply a more individualized approach to improve the quality of life for the patient.
