MR of parenchymal spinal cord signal change as a sign of active advancement in clinically progressive posttraumatic syringomyelia.
نویسندگان
چکیده
Extensive MR signal change in the craniad spinal cord parenchyma was found to be an ancillary sign of disease advancement in three patients with clinically progressive posttraumatic syringomyelia. This craniad margin of parenchymal spinal cord T2 hyperintensity resolved after cystoperitoneal shunt placement. There was a concomittant reduction or disappearance of the cyst in each instance, a halt in the progression of neurologic deficit, and some reversal of signs and symptoms.

In Re: The Presyrinx state: a reversible myelopathic condition that may precede syringomyelia.
BACKGROUND AND PURPOSE Alteration of CSF flow has been proposed to be an important mechanism leading to the development of syringomyelia. We hypothesize that a "presyrinx" condition attributable to a potentially reversible alteration in normal CSF flow exists and that its appearance may be caused by variations in the competence of the central canal of the spinal cord. METHODS Five patients wi...
متن کاملPosttraumatic syringomyelia
Post-traumatic syringomyelia is a clinical syndrome of delayed progressive myelopathy often corresponding to spinal segments distant from the level of original injury. Harvey Cushing described a syringomyelic syndrome in a patient with cervical gunshot wound. He viewed hematomyelia as the pathologic substrate of both – acute and delayed post-traumatic syringomyelia. The exact incidence is unkno...
متن کاملIncidence, management, and outcome of post-traumatic syringomyelia. In memory of Mr Bernard Williams.
OBJECTIVE To determine the incidence of clinically diagnosable post-traumatic syringomyelia (PTS). METHODS A population of 815 consecutive patients with traumatic spinal cord injuries was studied between January 1990 and December 1992. RESULTS Reviews of all records, full clinical evaluation, and thorough neurological examination of all patients disclosed 28 patients in whom PTS was confirm...
متن کاملThe MR appearance of syringomyelia: new observations.
Fifty-eight patients with spinal cord cavities were studied with MR imaging. Patients were separated into four groups, and the appearance of the cavities were compared. There were 24 patients (41.4%) with communicating syringomyelia (associated with the Chiari I malformation). Sixteen patients (27.6%) had posttraumatic syringomyelia, nine patients (15.5%) had associated tumors, and nine patient...
متن کاملThoracic Syringomyelia in a Patient with Amyotrophic Lateral Sclerosis
We report a patient with bulbar-onset, clinically defined, sporadic amyotrophic lateral sclerosis bearing an isolated syringomyelia of the lower thoracic portion of the spinal cord. This is a very unusual association between two rare and progressive disorders, both affecting the spinal motoneurons. Syringomyelia might have acted as a phenotypic modifier in this ALS patient.
