SUMMARY COMPUTERIZED CRANIAL TOMOGRAPHY FINDINGS IN MULTIPLE SCLEROSIS In this paper, computerized tomography findings in 35 multiple sclerosis patients who were classified as definite and probable according to clinical criteria were presented. Abnormal finding or findings were encountered in 19 cases (54 percent). Cerebral and/or cerebellar atrophy was the most common abnormality. We encountered this abnormality in 13 cases (37 %). The other but less frequent finding was hypodense lesions which showed periventricular localizations. This abnormality was observed in 7 cases (20 %). We found periventricular lesions which showed contrast enhancement in. one patient who was admitted to out: clinic with multiple sclerosis attack. ÖZET Bu yazımızda, klinik kriterlere göre kesin ve muhtemel multipl skleroz tanısı almış 35 hastadaki bilgisayarlı kranial tomografi bulguları sunulmuştur. Vakalarımızdan 19 tanesinde (% 54) anormal bulgu veya bulgular saptanmış¬tır. En sık rastlanan anormal bulgu serebral ve/veya serebellar atrofidir. Bu bulguya 13 vakamızda (% 37) rastladık. Diğer bir önemli fakat daha seyrek bulgu ise periventriküler lokalizasyon gösteren hipodens lezyonlarıdır. Bu bulguyu 7 hastamızda {% 20) gözledik. Multipl skleroz atağı ile kliniğimize başvuran bir hastada ise kontrast tutulum gös¬teren periventriküler lezyonlar saptanmıştır.
