Journal of Computer Assisted Tomography: May-June 1999 - Volume 23 - Issue 3 - p 351-353 Buy Abstract Three adult patients are reported with asymptomatic localized widening of the central canal of the spinal cord. These patients were followed for a period of 2-4 years by imaging and/or clinical history and physical examination without evidence of signs of symptoms related to spinal cord. This condition probably represents persistence into adult life of a fetal configuration of the central canal of the spinal cord. This process may be termed "idiopathic localized hydromyelia" to distinguish it from syringomyelia secondary to such causes as Chiari malformation, trauma, infection, or neoplasm. © 1999 Lippincott Williams & Wilkins, Inc.
