Abstract
The CT stereotactic method (Mundinger/Birg) arid the bioptic results of intracranial processes in 815 cases are reported. In 17% of the cases, no tumor was found, in contrast to the diagnosis estabhshed by modern imaging techniques (CT, MRI). The necessity of confirming the diagnosis of intracranial lesions to optimize the treatment plan is pointed out. Low mortahty and morbidity rates (0.6 and 3%) make this method acceptable for the patient, since misdiagnoses, mistreatment or omission of treatment can thus be avoided. The accuracy (0.6 mm) of CT stereotactic locahzation and biopsy makes the method reliable even for small lesions.
