title: [Tentorial meningiomas. Report of our series].
abstract: OBJECTIVE
  The main objectives of this report are to describe the clinical and radiological features, surgical management, complications, and final outcome of patients with a tentorial meningioma.
  
  
  METHODS
  This is a retrospective study of 25 patients operated on for tentorial meningiomas at our department since december 1975 to may 2002. All the patients, except the first, were diagnosed by computed tomography; in 13 of them a magnetic resonance imaging was performed too; in 14 patients, diagnosis was completed with cerebral arteriography. The preoperative clinical condition, the interval between the first symptoms and the date of the operation, the postoperative morbidity and the recurrence are analysed.
  
  
  RESULTS
  There were 20 women and 5 men of ages ranging from 35 to 79 years (average of 54.6). Surgical removal was considered radical (Simpson I-II) in 22 patients. Of them one had a recurrence 25 years after the operation, another had three recurrences, in two years, that were reoperated, and a third one had recurrence at five years who did not require surgery. The postoperative mortality was 8%. The mean follow-up period was of 5.3 years. The final outcome was good recovery in 19 patients, moderate disability in 1 and death in 4.
  
  
  CONCLUSIONS
  Despite the advances in Neuroradiology and Microsurgery, these tumors represent a challenge for the neurosurgeon, due in some cases to a large tumor size and extension to critical areas. A removal as complete as possible allows minimizing the recurrence risk.
