title: The occurrence of tumors of the central nervous system in a clinical observation.
abstract: Brain tumor is an abnormal growth of cells in central nervous system (CNS). The most common primary brain tumors are: gliomas, meningiomas, pituitary adenomas and craniopharyngiomas. The secondary group are metastatic tumors. About 25% patients with cancers have metastasis to CNS.
  
  
  OBJECTIVE
  The aim of this study was to evaluate the most common symptoms and localization of brain tumors, time from first symptoms to diagnosis and patients' survival rate.
  
  
  METHODS
  In this retrospective study 106 patients with primary and metastatic brain tumors hospitalized in Military Institute of Medicine from 2007 to 2012 year were investigated.
  
  
  RESULTS
  The most common cause of metastases to brain is non-smallcell lung carcinoma. The most frequent symptom of brain tumor is headache but very often patients have seizures, vomits, arms and legs weakness. The mean time of life for patients with gliomas was 9 month and 13 days for patients with brain metastases.
  
  
  CONCLUSIONS
  It occurred that patients with primary and secondary brain tumors lived shorter than it is described in literature. In group of patients with metastases to brain 60% had one or two brain tumors so they could be treated with surgery and prognosis for them was better.
