title: A classification of lesions around interventricular foramen and its clinical value.
abstract: OBJECTIVE
  Lesions around interventricular foramen are difficult to remove for their important adjacent structures. We classify these tumors according their location on Magnetic Resonance Image (MRI) to help us resect these lesions.
  
  
  METHODS
  Thirty-two tumors around the interventricular foramen were studied according their location and anatomic relations in MRI.
  
  
  RESULTS
  Tumors around interventricular foramen were classified into three types. The first one mainly locates in lateral ventricle and the second one growth both in lateral ventricle, interventricular foramen and third ventricle, while the third one mainly in third ventricle. Different surgical approaches were adopted according their classification and the patients recovered well.
  
  
  CONCLUSIONS
  This classification can help us to chose the surgical approach for these tumors.
