title: Computed tomography in the diagnosis of syringomyelia.
abstract: We describe the usefulness of computed tomography (CT) in the diagnosis of syringomyelia in 12 patients for whom the diagnosis had remained unconfirmed with other diagnostic methods. In 7 of these patients, CT myelography revealed an intramedullary cavitation filled with contrast medium. In 3 patients, the cavitation was not filled, and positive contrast medium was not used in another 2. In these 5 cases, however, CT visualized low-density areas within the cord. CT would seem to be the most preferable method for confirming the clinical diagnosis of syringomyelia and is particularly useful in atypical cases.
