Abstract
Patients with pathologically confirmed diagnoses of meningioma were examined to investigate the hypothesis that left-hemisphere lesions are smaller or declared earlier than right-hemisphere lesions. 77 patients were examined with regard to age at presentation and nature of symptoms. In addition CAT scan films of 47 patients were obtained for measurement of lesion size. There were no differences between right and left lesion groups with regard to size of lesion or age at presentation. Subgroups of patients with lesions in frontal association areas also did not differ. Some relationships were discovered between lesion location and nature of symptoms.
