CT stereotactic biopsy for optimizing the therapy of intracranial processes

The CT stereotactic method (Mundinger/Birg) and 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 established by modern imaging techniques (CT, MRI). The necessity of confirming the diagnosis of intracranial lesions to optimize the treatment plan is pointed out. Low mortality 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 localization and biopsy makes the method reliable even for small lesions.
