[Intracranial tumors simulating neurological infections].

The clinical manifestations were analysed in 16 patients with expanding intracranial lesions hospitalized in the period from Jan 1 1980 to Aug 31 1990. They had been admitted to hospital with the diagnosis of suspected neuroinfection. The initial manifestations and abnormalities in neurological examination might have suggested inflammatory processes in the central nervous system. Only further diagnostic procedures, especially emergency ones such as angiography and CT of the brain made possible establishing of final diagnosis and qualifying the patient for surgical intervention. The authors stress that expanding intracranial lesions should be always taken into account in patients with clinical and CSF abnormalities persisting despite ruling out of neuroinfection.
