Complex closed spinal dysraphism: lipomyelocele and diastematomyelia. Fetus at 22 weeks’ gestation. a Sagittal T2-weighted HASTE image shows a deformity of the spinal canal completely covered by soft tissues (arrows). b Coronal image showing the widening of the spinal canal at the lumbar level (white arrows) and abnormally low termination of the medullary cone (black arrow) below the kidneys. c CT study after birth shows the deformed, widened spinal canal (arrowheads) and soft-tissue calcification behind the bone defect (white arrows). d Sagittal T1-weighted MRI image obtained after birth shows the abnormally low medullary cone, a lipomatous component within the spine (white arrows), and soft-tissue calcification (black arrow). e Axial T1-weighted image showing spinal cord duplication (black arrows) and the lipomatous component within the spine (asterisk). f Photograph of the patient after birth. g Sagittal diagrams of the anomaly
