Bu çalışmada, halsizlik,
kafasını sağa sola çarpma, yürümede güçlük, görmede bozukluk gibi klinik
bulgularla ötenazisi yapılan, 17 yaşlı, erkek bir kedide intrakranial
psammomatöz meningioma olgusu tanımlandı. Hayvan sahibinin isteği ile kedi
ötenazi edildi. Histolojik incelemede,
atipik özellikler gösteren, mekik şekilli, belirgin eozinofilik sitoplazmalı,
yuvarlak çekirdekli hücrelerin aralarında yoğun kollajen demetlerin varlığı
görüldü. Ayrıca çok sayıda konsantrik lamellasyonlardan oluşan girdapların merkezlerinde
bazofilik mineralizasyon alanlarının olduğu psammom adacıkları dikkati çekti.
Bu yapıların aralarında yarıklar halinde kollesterin kristallerinin olduğu fark
edildi. Sonuç olarak kedilerde sık rastlandığı bildirilen ancak ülkemizde ilk
kez bir kedide saptanan intrakranial psammomatöz meningioma makroskobik ve
mikroskobik bulguları ile tanımlanmıştır.

In the
present study, intracranial psammomatous meningioma was described in a 17 years
old, male cat is submitted to clinics with history of weakness, incoordination,
difficulty in walking and oversight. The animal is euthanatized with request of
owner of cat. Histological examination revealed the presence of dense collagen
bundles between the round nucleated cells with atypical features,
shuttle-shaped, marked eosinophilic cytoplasm. In addition, psammom islands,
where basophilic mineralization areas are located in the centers of vortices
composed of many concentric lamellations, have been noted. At necropsy, the
cadaver is evaluated systematically as to routin necropsy method. Collestrin
clefts were seen between collestrin crystals. As a result, although intracranial
psammomatous meningioma seen frequently in cats, the tumour was described with
macroscopic and microscopic findings in a cat, in our country initially.
