Özet
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
