Diastematomyelia is a congenital dysraphism of the spinal cord in which the affected segment is longitudinally divided by a band of fibrous tissue, cartilage, or bone. Diastematomyelia has been well described in the cervical, thoracic, lumbar, and sacral spinal cord; this paper presents a case involving the basicranium. Based on the early embryologic development of the basicranium and brain, this case demonstrates that the same mechanisms proposed as the origin of spinal diastematomyelia may also operate at a more cephalad level.
