title: [Diagnosis and surgical treatment of pituitary microadenoma].
abstract: OBJECTIVE
  Through the experiences of clinic picture and the radiologic characteristics of eleven cases of micropituitary adenomas, the early diagnosis and surgical indications were discussed.
  
  
  METHODS
  Intensified CT and MRI were used to compare their significances in the diagnosis of micropituitary adenomas. Kaltai incision of the nares and transsphenoidal approach were adopted in these cases.
  
  
  RESULTS
  The bulging of the upper border of the pituitary gland and the shifting position of the pituitary stalk observed in the intensified MRI are the pathognomonic signs for the diagnosis of micropituitary adenoma. The operation was stopped due to hemorrhage in one case. The average following up was 3.2 years past operative death in the second month in one case, operative failure in one case and loss of following up in one case.
  
  
  CONCLUSIONS
  Strict selection of surgical indications must be done necessary after careful study of MRI.
