Zusammenfassung

In der Diagnosestellung von Vestibularisschwannomen ist die Bildgebung mittels Magnetresonanztomographie (MRT) der Goldstandard. Senitivität und Spezifität liegen bei fast 100%. Mit der MRT lässt sich der Tumor entdecken und seine Ausdehnung beschreiben, was dem potenziellen Operateur auch prognostische Hinweise liefert. Eine Vorhersage für das Wachstumsverhalten der Tumoren ist damit aber nicht möglich. Eine subtile Analyse der Bildbefunde erlaubt fast immer die differenzialiagnostische Abgrenzung gegenüber anderen Entitäten. Sowohl bei operierten als auch bei nicht operierten Patienten sind Verlaufskontrollen eine weitere wichtige Aufgabe der MRT. Die Computertomographie (CT) ist nur noch zur Operationsvorbereitung und in der unmittelbar postoperativen Phase nötig.

Abstract

Magnetic resonance imaging (MRI) is the diagnostic gold standard in vestibular schwannoma. Sensitivity and specificity are both close to 100%. MRI detects the tumour and describes its extension, thereby giving the potential surgeon prognostic clues. Prediction of tumour growth, however, is not possible. Careful analysis of imaging findings almost always enables differentiation from various other disease entities. Follow-up of surgical as well as non-surgical patients is another important role of MRI. Computed tomography (CT) is restricted to pre-surgical workup and to the immediate postoperative period.
