Concurrent diastematomyelia and syringomyelia.

A case of concurrent diastematomyelia and syringomyelia in a 6-year-old girl was presented. She had hypertrichosis and dimple in the lumbosacral region. X-ray and CT myelography demonstrated spina bifida, low placed conus, tight filum terminale, and diastematomyelia. In addition to these abnormalities, MR imaging demonstrated syringomyelia that was not detected by other radiographic studies.Because embryopathologically, diastematomyelia and syringomyelia may occur simultaneously, the possibility of syringomyelia should be carefully evaluated in patients with diastematomyelia. And MR imaging will be an excellent tool to deliniate the presence of syringomyelia as well as other associated abnormalities.
