The role of magnetic resonance imaging in the diagnosis of endocrine tumours of the sellar region in children.

Most tumours of the sellar region in children give rise to one or more of the following endocrinological symptoms; anterior pituitary hypersecretion syndromes, growth delay, diencephalic syndrome, diabetes insipidus or precocious puberty. Magnetic resonance imaging enables the visualization of tumours, providing recognizable characteristics allowing the relatively easy recognition of pituitary adenomas, craniopharyngiomas, germinomas, hamartomas, hypothalamic astrocytomas as well as granulomatous proliferations.
