[Diastematomyelia in adulthood].

A case of a 43-year-old female patient with a diastematomyelia from T11 to L4 is reported. The correct diagnosis was only made in adulthood, although clinical symptoms had been present since childhood. This case is compared with the few other cases known in the literature. The combination of myelography, CT and NMR proved to be most valuable for making this diagnosis.
