The first case, detected at 20 weeks' gestation, had a lumbar meningocele. At 30 weeks' gestation, direct US visualization revealed the division of the spinal cord into two hemicords. This patient illustrates an isolated type II diastematomyelia with a favorable prognosis. The second case, detected at 22 weeks' gestation, presented with disorganization of bony process of the vertebral column with a midline echogenic bony spur, asymmetrical hemicords, and a foot malposition. Fetal MRI at 26 weeks' gestation and CT/3D reconstructed at 32 weeks' gestation confirmed a type I diastematomyelia with orthopedic malposition. The third case, detected at 22 weeks' gestation, presented with widening of the lumbar canal and scoliosis. Prenatal work-up (US, MRI) disclosed other visceral malformations (pelvic kidney), which led to the assumption of a complex polymalformative syndrome. The pregnancy was terminated. Fetopathologic examination disclosed even more visceral malformations (anal atresia and unicorn uterus).
