Summary

A 12-year-old domestic shorthair cat was presented with neurologic signs localized to the forebrain. Magnetic resonance imaging (MRI) of the brain revealed a space occupying lesion within the third and the lateral ventricles. The lesion had areas of disparate signal characteristics and exerted a mass effect on the surrounding parenchyma and ventricular system. The histologic examination identified the co-existence of two intraventricular masses: a meningioma and a choroid plexus cholesterol granuloma.

Zusammenfassung

Eine 12-jährige Europäisch-Kurzhaar-Katze wurde mit zentralnervösen Ausfallerscheinungen vorgestellt, die sich in der neurologischen Untersuchung auf das Vorderhirn lokalisieren ließen. Die magnetresonanztomographische Untersuchung des Kopfes zeigte eine Raumforderung innerhalb des dritten Ventrikels und der Seitenventrikel. Die Läsion wies Regionen mit unterschiedlichem Signal- und Kontrastanreicherungsverhalten sowie einen Masseneffekt auf das umgebende Gehirnparenchym und Ventrikelsystem auf. In der histologischen Untersuchung konnten zwei Massen verschiedener Ursprungsgewebe im Ventrikelsystem identifiziert werden: ein Meningiom und ein Cholesterolgranulom des Plexus choroideus.
