Perisellar tumours including cysts, hamartomas, and vascular tumours
Approximately 80% of symptomatic tumours in the pituitary region are pituitary adenomas and further 10% are craniopharyngiomas. Among the remaining 10%, a considerable number of rare tumour entities have to be considered (Box 2.4.3.1) which makes the differential diagnosis sometimes difficult. Endocrinological, neuroradiological, and ophthalmological evaluation is the indispensable diagnostic triad to identify typical features in nonadenomatous perisellar tumours, and to provide diagnostic accuracy. This chapter presents typical clinical aspects of various nonadenomatous sellar tumours and the differential diagnostic value of specific symptoms. The current therapeutic strategies are also described.
