Twenty-day-old female infant presented with multiple back masses, 2 cystic and one solid at both dorsal and lumbar levels. A 3D reconstruction image of bony spine showing multilevel segmentation anomalies with complete splitting of lower 6 thoracic vertebrae into 2 separate spinal canals. B Axial T2WI at upper dorsal level showing 2 hemicords herniating into two sacs in keeping with hemi-myelomeningoceles, on the left side shows focal rupture (white arrow). C Axial T2WI at upper lumbar level showing another intact myelomeningocele containing two hemi cords, note left sided hydronephrosis. D Sagittal fat suppressed image of whole spine showing upper dorsal and lumbar myelomeningoceles (white arrows) as well as lower dorsal heterogenous fat containing lesion (white star), note associated hydrocephalus. E Coronal T2WI showing segmental lower dorsal splitted bony elements with heterogenous mass in-between containing both fatty and bony elements histopathologically proven to be teratoma. F, G Bed side axial USG images showing two hemicords within single dural sheath (white arrows). H Axial CT image bone window at lower dorsal level showing splitted spinal canal. Type of spinal dysraphism: Split notochord (Diastematomyelia) with myelomeningoceles
