Abstract (2. Language): 
Intracranial Calcifications Mimicking Incidental Aneurysms On Magnetic Resonance İma-ging. Although Magnetic Resonance Imaging (MRI) is a very sensitive tool in the diagnosis of central nervous system diseases, it may be insufficient in the detection of some lesions; es-pecially those containing calcifications. 46 year-old man was being treated for seizures in the epilepsy division of Neurology Department of İstanbul School of Medicine. He was referred to our department vvhen 0.5 cm and 1 cm size signal void aneurysms were detected in the left Sylvian fissure at the location of the middle cerebral artery bifurcation and medial to the right temporal lobe, respectively on crani-al MRI. Neurological exanıination revealed no abnormality and a digital subtraction angiog-raphy was performed to assess the incidental aneurysms. No aneurysm or other pathology was detected in the angiogram. Cranial Computed Tomography (CT) showed that the lesions were hyperdense revealing that the lesions were calcified. He was sent back to the Neurology Department for follow up. This paper presents a patient with seizures, who had MRI findings compatible with aneurysms, negative on cerebral angiography and apparently calcified on CT.

Abstract (Original Language): 
Santral sinir sistemi hastalıklarının tanısında manyetik rezonans görüntüleme çok duyarlı bir tanı aracı olmasına rağmen kalsifikasyon gibi bazı patolojilerin değerlendirilmesinde yetersiz kalmaktadır. Nöbet nedeniyle İstanbul Tıp Fakültesi Nöroloji Anabilim Dalı, epilepsi polikliniğinde tedavi edilmekte olan 46 yaşındaki erkek hasta kranyal manyetik rezonans görüntülemesinde sağ temporal lob medial kesiminde 1 cm çapında, sol silviyan fissürde sol orta serebral arter bifur-kasyon düzeyinde 0,5 cm çapında Tl ve T2-ağırlıklı görüntülerde hipointens anevrizma ile uyumlu görünüm saptanması üzerine kliniğimize sevk edildi. Nörolojik muayenesi normal olarak değerlendirilen hastanın olası insidental anevrizmalarını saptamak için serebral dijital substraksiyon anjiografi incelemesi yapıldı. Bu incelemenin normal bulunması üzerine sağlanan bilgisayarlı beyin tomografisinde anevrizma düşünülen bölgelerde hiperdens lezyon saptandı Hiperdens lezyonların kalsifikasyon olduğu düşünüldü. Nörolojik muayenesi normal olan hasta nöroloji epilepsi polikliniğine sevk edildi. Bu çalışmada nöbet kaynağını bulmak için kranyal manyetik rezonans incelemesi sonucu anevrizma şüphelenilen; serebral dört damar anjiografisi negatif değerlendirilen; kranyal bilgisayarlı tomografisinde kalsifikasyon saptanan olgu sunulmuştur.
