title: [Correlation between clinical apparatus-based differential diagnosis and neuropathological diagnosis in patients with AIDS].
abstract: BACKGROUND
  During the course of HIV infection, the majority of patients develop opportunistic cerebral neuro-manifestations. If conventional diagnostic tools are not sufficient, a stereotactic biopsy is often necessary.
  
  
  METHODS
  In order to evaluate the correctness of the clinical diagnosis of cerebral neuro-manifestations in HIV-infected patients, we compared the results of cerebral biopsy or autopsy with the previous clinical diagnosis. A total of 19 biopsies and 49 autopsies could be analyzed.
  
  
  RESULTS
  Except for HIV-associated encephalopathy, we detected a very high conformity between the clinical and the neuropathological diagnoses. We obtained the best sensitivity for progressive multifocal leukoencephalopathy (PML), whereas for cerebral toxoplasmosis the worst sensitivity and specificity was identified.
  
  
  CONCLUSIONS
  We conclude that the diagnosis of PML can be made on clinical grounds alone, whereas the diagnosis of cerebral toxoplasmosis and lymphoma often requires a biopsy, which should be performed early.
