The MRI sequences demonstrate:
low lying spinal cord terminating at L4-L5 level
diastematomyelia type I at L4 (hemicords separated by a bony spur)
spina bifida at several levels with no meningocele or myelomeningocele
mild lumbar scoliosis of left-sided convexity
Case Discussion
MRI features of diastematomyelia, also known as a split cord malformation type I which is the classic type characterized by:
duplicated dural sac with midline spur (osseous or osteocartilaginous)
associated hydromyelia is common
vertebral abnormalities such as hemivertebrae, butterfly vertebrae, spina bifida
cutaneous pigmentation, hypertrichosis, hemangioma are common
