title: Stereotactic radiosurgery for aggressive papillary tumor of the temporal bone: case report.
abstract: BACKGROUND
  Papillary tumors of the temporal bone are very rare neoplasms that show locally aggressive behavior though they have low-grade histologic features. The best treatment for these tumors is a radical resection. However, if the tumor is very large, local invasiveness and hypervascularity can prevent surgeons from achieving a complete resection. As an additional treatment for the residual tumor, it remains controversial whether radiation therapy has any role.
  
  
  METHODS
  The authors describe a 53-year-old woman who suffered from left-sided tinnitus, hearing loss, and diplopia due to a large aggressive papillary tumor of the temporal bone. Radiosurgery was very effective for the tumor, which had regrown a few years after conventional radiation therapy and chemotherapy.
  
  
  CONCLUSIONS
  The authors conclude that radiosurgery should be considered as an option for the treatment of aggressive papillary tumor of the temporal bone.
