Abstract

The early diagnosis of intracranial tumours in statu nascendi is not yet possible. Since many lesions can attain quite a large size without clinical manifestations, diagnosis cannot be made before initial symptoms have become obvious. Prior to the establishment of computed tomography (CT) in the early 1970s, the diagnosis of a brain tumour could only be accomplished when the lesion was large enough to cause indirect morphological signs such as a significant shift of midline structures or displacement of normal vessels, or when pathological vasculature could be demonstrated. CT initiated a diagnostic revolution as brain tissue could, for the first time, be visualised directly. Magnetic resonance imaging (MRI) has further improved the possibility of direct diagnosis.
