Neoplastic encephalopathy in the light of 2 observed cases

: The authors report two cases of neoplastic encephalopathy. In one patient with oviduct carcinoma it had the form of cerebellopathy. In the other case of renal carcinoma it appeared as encephalopathy with a nearly exclusive involvement of cerebral hemispheres. The reaction of microglia, lymphocytes and diffuse demyelination found in these cases are regarded by the authors as a result of autoimmunization in the course of malignant neoplasm. Attention is called to the importance of axial computer tomography in the intravital diagnosis of this encephalopathy.
