[Computed tomographic brain scanning in the diagnosis of metastatic neoplasms (author's transl)].
Clinical investigations and computed brain scanning were done in 305 patients with primary extracerebral malignant tumours. One third of the patients had cerebral metastases. In most patients with brain metastases extracerebral secondary tumours were known already. Silent brain metastases were present in only 0.6% of all investigated tumour patients. All other patients had either objective neurologic-psychiatric defects or a least symptoms (headache, vomiting). Use of cranial computed tomography in all tumour patients as a pure screening method is thus not justified. The indication for the investigation is dependent on the clinical symptomatology. However, not only objective neurologic-psychiatric defects must be taken into account, but also occurrence of new symptoms.
