Neurological manifestations of malignant diseases.

Four hundred and sixty three patients with malignant diseases were studied over a period of two years; of these, 53 (11.44%) had neurological syndrome, both metastatic (32) and non metastatic (21). The lymphoma-leukaemia group accounted for 34 of the 53 cases. The maximum manifestations were seen in the 21-40 years age group, with male preponderance. The metastatic manifestations were as a result of cerebral (16), brainstem, cerebellar (12) and cord (4) deposits. These were confirmed by CT scan and myelogram. The non metastatic manifestations were peripheral neuropathies (7), leukoencephalopathy and intracranial haemorrhage (6 each), and myasthenic syndrome and myopathy (one each). These findings were confirmed by electrophysiological studies, CT scan, and histopathological examination. Autopsy studies were carried out in 12 of the 53 cases.
