title: [Differential diagnosis of brain tumors and chronic subdural hematomas according to echoencephalographic and electroencephalographic findings].
abstract: Examination of 15 patients with tumors of the brain in whom the presence of subdural hematomas could not be excluded and of 27 patients with chronic subdural hematomas revealed that displacement of the M-echo was 8 +/- 0.43 mm on the average in chronic subdural hematomas and 5.6 +/- 0.43 mm in tumors. EEG abnormalities were observed in 100% of cases with tumors and were mostly of a coarse character. In chronic subdural hematomas EEG abnormalities were relatively rare (18.5%) and were less manifested than those in tumors. The statistical significance of the differences evidently allows the sign of the dissociation of the EEG and Echo-EG data in chronic subdural hematomas to be used for the differentiation of the disease from tumors.
