title: Atypical syringomyelia without cavity in a patient with Chiari malformation and hydrocephalus.
abstract: METHODS
  A case report is presented.
  
  
  OBJECTIVE
  To investigate atypical syringomyelia without cavity.
  
  
  BACKGROUND
  Syringomyelia without frank cavity is rarely reported. The MR imaging appearance of this atypical syringomyelia may help to understand the mechanism leading to the development of syringomyelia.
  
  
  METHODS
  Data are given for one patient who underwent MR imaging; she had Chiari malformation and hydrocephalus.
  
  
  RESULTS
  The patient had enlarged spinal cords, and gray matter T2 prolongation without cavitation occurred in association with continued cerebrospinal fluid obstruction in upper spine and improved after surgical intervention 14 days later.
  
  
  CONCLUSIONS
  Obstruction of the cerebrospinal fluid pathways in the upper spine may result in spinal cord gray matter T2 prolongation that is reversible after restoration of patency of cerebrospinal fluid pathways and stress the importance of timely intervention to limit progression to syringomyelia.
