title: Tumours of the limbic and paralimbic system.
abstract: 240 patients with tumours of the limbic and paralimbic areas are presented. The following tumour growth patterns have been observed: they remain isolated to areas within the allocortex; they spread throughout allocortical regions; they spread from allocortical to mesocortical zones. With the exception of advanced malignant tumours there seems to be a tendency for tumours to spare the adjacent neocortical and medial structures. The tumours can be approached and extirpated using the trans-Sylvian approach and microneurosurgical technique. 56% have been histologically benign. 60% were below 40 years of age. Seizures were the leading manifestation (77%). In 95% the postoperative results were good. There was no peri-operative mortality.
