title: Vertebral pneumatocyst. A case report.
abstract: METHODS
  This study illustrates intraosseous pneumatocyst of the vertebral body, a benign lesion.
  
  
  OBJECTIVE
  To review the incidence and location of this benign lesion during a 1-year period.
  
  
  BACKGROUND
  Intraosseous pneumatocyst is a rare benign condition, commonly seen in iliac bone or sacrum. The etiology of this entity is unclear. Other locations of these lesions are very rare, and only a few isolated cases are reported in the literature.
  
  
  METHODS
  In the last year (1994-1995), vertebral pneumatocyst was incidentally found in four patients who underwent computed tomography examination for presumptive discal lesion. Axial computed tomography with 2- and 4-mm slice thickness was performed.
  
  
  RESULTS
  The typical computed tomography patterns of intraosseous pneumatocyst involving the cervical, dorsal, or lumbar spine were found. The bony structure and joints were normal. To the best of our knowledge, intraosseous pneumatocyst located in the spinal process has not been reported.
  
  
  CONCLUSIONS
  Intraosseous pneumatocyst is a benign lesion. Biopsy and follow-up are unnecessary.
