    (Wolters Kluwer Health, 2015) Kotan, Dilcan; Sayan, Saadet; Polat, Pınar; Özözen Ayas, Zeynep
    Dermoid cysts are rare cystic tumors originating from ectodermic cells within the intracranial region. These cysts emerge during closure of the neural tube during embryological development. The symptoms are generally incidental and nonspecific. If rupture occurs, the cyst contents propagate through the subarachnoid space and the ventricular system. The dramatic appearance of subarachnoid and cisternal fat droplets facilitates the diagnosis of dermoid cyst rupture by computer tomography and magnetic resonance imaging. Herein, we present a case of ruptured dermoid cyst in an elderly patient. The patient presented with minor symptoms such as nonspecific headache and dizziness; dermoid cyst rupture was diagnosed by observing the fat droplets disseminate into the subarachnoid and cisternal spaces that extend from the left cerebellopontine angle, adjacent to the left carotid channel, to the cavernous sinus, using computer tomography and magnetic resonance imaging.

    Bilateral vertebral artery stenosis present with vertigo
    (2013) Kotan, Dilcan; Sayan, Saadet; Polat, Pınar; Acar, Bilgehan Atılgan
    Of ischaemic stroke patients, about 25% rise from the posterior or vertebrobasilar system. The ischaemia of vertebral arteries may emerge for different vascular pathological reasons, at different localisations and with different clinical findings. Despite its low morbidity and mortality risk, early diagnosis and treatment is of importance. Vertebrobasilar ischaemia symptoms can be observed clinically such as vertigo, tinnitus, double vision, headache, hypokinesis and hearing disorders, etc. In this article, a 42-year-old stroke patient case is presented, who applied to the emergency service with vertigo and then, was diagnosed with bilateral vertebral artery stenosis by means of cranial MR angiography.

    Dev i?nternal karoti?d arter anevri?zmali bi?r olgu
    (Turkish Society of Cerebrovascular Diseases, 2013) Kotan, Dilcan; Ünal, Gözde; Sayan, Saadet; Polat, Pınar; Bölük, Ayhan
    Çapı 2,5 cm den büyük olan anevrizmalar, dev anevrizma olarak sınıflandırılır ve bütün intrakranyal anevrizmaların yaklaşık %5-8’ini oluşturur. Dev intrakranyal anevrizmalar subaraknoid kanama, kitle etkisi, nöbet ve tromboemboli gibi bulgularla klinik gidiş gösterirler. Dev anevrizmalar sadece büyüklükleri ile değil aynı zamanda genellikle geniş ve kalsifiye olan boyunları, kranyal sinirlere yakınlıkları ve içerdikleri trombüs nedeniyle ciddi cerrahi güçlüklere neden olur. Yavaş ilerleyici damar anormallikleri gösteren anteriyor intrakranyal dolaşımın dev anevrizmaları nadirdir, genellikle rüptür öncesi nörooftalmolojik semptomlar ile başvurur. Burada, kitle etkisiyle multipl kranyal sinirleri etkileyerek semptom veren, MR anjiyografi ile internal karotid arter intrakavernöz segmentinde dev anevrizması saptanan 77 yaşında kadın olgu sunuldu.
