title: Three-dimensional images for surgical plan of giant sacral schwannoma.
abstract: OBJECTIVE
  Documentation of three-dimensional (3D) images of a giant sacral schwannoma with intrapelvic expansion.
  
  
  METHODS
  Nagoya University, Nagoya, Japan.
  
  
  RESULTS
  3D computed tomography (3D CT) showed a destructed bony region clearly. 3D CT angiography clarified the positional relationship between tumor and iliac arteries. Resection procedure was safely completed based on these 3D evaluations.
  
  
  CONCLUSIONS
  3D images were helpful to make a surgical plan and to complete this complicated resection combined with sacroiliac reconstruction.
