[Incidentaloma in a 16 years old girl -- 2 year observation]

Adenomas of the hypophysis are tumors of the CNS which are on the third place in the frequency of appearance, which cause disturbances of hypophyseal function. In children incidentaloma is seldom observed. The authors present a 16-year-old girl who was admitted to the clinic because of amenorrhoea and an increased growth velocity during the last year. The MRI examination of the hypophysis proved a hypophyseal adenoma. Hormonal laboratory examinations do not show any hormonal activity of the observation. The girl's case is presented because the diagnosis of an incidentaloma is exceptionally rare in this age group.
