Zusammenfassung

Die Sellaregion und die Pinealisloge sind relativ häufige Lokalisationen von Tumoren im Kindesalter, allerdings zeigt sich ein anderes Spektrum der hier anzutreffenden Raumforderungen als bei Erwachsenen. Die häufigste intra- und supraselläre Raumforderung bei Kindern ist das Kraniopharyngeom, während Hypophysenadenome selten sind. Als Prädilektionsstelle von Keimzelltumoren bei pädiatrischen Patienten gilt die Pinealis, bei Erwachsenen findet man sie hauptsächlich in den Gonaden. Die Rolle der Bilddiagnostik besteht in der frühzeitigen Detektion der Läsionen, der adäquaten Darstellung ihrer Charakteristika und des Bezugs der Raumforderung zu den angrenzenden Strukturen.

Abstract

The (supra) sellar and pineal regions are relatively common sites for pediatric brain tumors; however, the distinct spectrum of space-occupying lesions is in marked contrast to that of the adult population. Craniopharyngeoma represents the most common intrasellar and/or suprasellar lesion in children, whereas the pituitary adenoma typical for adults- is generally rare. The pineal region is a predilection site for germ cell tumors in pediatric patients, while in adults this cancer category is largely confined to the gonads. The role of imaging is in the early detection of lesions, adequate demonstration of the characteristics and delineation of the complex anatomical relationship to adjacent vital structures.
