Abstract

Suınmary: A 14-year-old, female cat demonstrating blindness, paralysis, and encephalitic symptoms (also suspected ofrabies) was examined. During the last ten days a graduallose of apetite, ineoordination and hitting the objects on her way when she walks, suddenjumpings followed by a deep sleep were noticed. A nut sized, grayish-pink colored, well
defined mass localizcd in the left (ılfactory bul b area was the only necropsy findingo The mass
caused deformation of hemisphercs, and marked flattening of su1ci and gyri by its existence
and exerted pressure by growing in expenee of brain volume. The cerebellum was pushed
backward, into the occipital foramen magnum, and its ,,"orms was flattened too, by the pressure of bone. No gross infiltration or neoplastic invasion was detectable, though the meninges were seemed edematous and swollen with some opacity around the tumor mass. The
detailed histologic examinations revealcd the onion-like arrangement of well dcfined tumor
eells, precipitated ca1cium in the central portion of whorls resembling a smail blood vessel
that underwent to hyalinous degeneration, as wc re ealled psammoma bodics based on their
gross appearanee. Some necrotic are as wc re seen in tumor, perivascular lymphoid infiltration
and neuronal aegeneration were present in the brain (meningo-eneephalitis)
Özet: Körük, paraliz ve ensefalit beldekleri gösterip kuduzdan da şüpheli
