Abstract

Ten cases of unusual lesions involving the sella turcica are presented to demonstrate their variance with neurologic, endocrinologic, and neuro-radiologic principles. These lesions, as well as other lesions described inthe literature, would indicate the hazard of making a specific diagnosis without biopsy. The application of the transsphenoidal microscopic approach to the pituitary fossa makes biopsy of such lesions carry less morbidity, and in many cases small or contained within the sella.
