[Neuroradiologic diagnosis of diastematomyelia]

A report is given on 5 patients with diastematomyelia, in one case the fissure formation of the marrow being without a provable septum. In the frequently very complex pathological-anatomical conditions of the spinal dysraphic malformation, CT can be a considerable help. In combination with metrizamide myelography, details of the marrow parts and their envelopes can be demonstrated. The preoperative planning of the marrow separation becomes more exact. Other causes of a deep spinal marrow level (tethered cord) such as teratomas can also be recognized by CT.
