[An evaluation of methods of diagnosing central nervous system metastases (author's transl)].

In 50 cases of histologically identified metastases of the central nervous system it was found that in cases of breast cancer and malignant melanomas the diagnosis of the primary tumor is the key to the diagnosis of the metastasis; bronchial carcinomas are usually found upon diagnosis of cerebral metastases; angiography, color scintigraphy and the computer tomography have a false negative rate of 10--15%, in cerebrospinal fluid protein levels are often increased (64%), and tumor cells are found in 18%.
