title: [Clinical analysis of 271 cases of orbital inflammatory pseudotumors].
abstract: OBJECTIVE
  To analyze and summarize the clinical signs, the diagnostic and differential diagnostic value of imaging examination in orbital inflammatory pseudo-tumors and the comparison of the therapeutic effect of various treatments.
  
  
  METHODS
  Retrospectively, 271 cases (303 eyes) of orbital inflammatory pseudotumors were analyzed.
  
  
  RESULTS
  Ultrasonography and CT had their diverse manifestations according to the different characterizations of the histopathology of tumors. B-ultrasonography showed a tumor with low reflection and strong sound transmission in diffuse lymphocytic infiltrative pseudotumor. A tumor with fibro-proliferative lesion had low reflection, weak sound transmission and irregular border. CT showed lesions touching closely with the globe. Steroid and radiotherapy were effective for diffuse lymphocytic infiltrative pseudotumors. The various therapies were not effective for fibro-proliferative lesions.
  
  
  CONCLUSIONS
  Imaging examinations are valuable for the diagnosis, differential diagnosis, the evaluation of histopathology types and the choice of treatment for orbital inflammatory pseudotumors.
