Abstract
A 15-year-old female patient with no previous health problems was admitted our clinic with syncope. Cranial computed tomography of the patient showed a 6.5x3.5 cm mass lesion with heterogeneous weak hyperdensity in the left frontoparietal region adjacent to the internal tabula. There was a hypodense zone of edema around the lesion. Following contrast medium injection, significant contrast enhancement was observed. In the anterior portion of the body of the left lateral ventricle and in the left frontal horn, we found obliteration which was
secondary to the edema. The mass was excised by left frontotemporal craniotomy. Histopathological findings were found to be consistent with ependymoma, WHO Grade III. We discuss here a case with a diagnosis of an ependymoma with an extraaxial location and anaplastic histomorphology, in the light of current literature.

Daha önce sağlıklı olan 15 yaşındaki kadın hasta senkop belirtileri ile kliniğimize başvurdu. Kraniyal tomografide sol frontopariyetal bölgede internal tabulaya komşuluk gösteren heterojen zayıf hiperdens yapıda 6,5x3,5 cm boyutlarında kitle lezyonu tespit edildi. Lezyon çevresinde hipodens ödem sahası vardı. Kontrast madde enjeksiyonu sonrası belirgin kontrast madde tutulumu izlendi. Sol tarafta lateral ventrikülün gövde kesiminin anterior kısmında ve sol frontal hornda ödeme sekonder obliterasyon görüldü. Sol frontotemporal kraniyotomi ile kitle eksize
edildi. Histopatolojik bulgularla olgu clear cell ependymoma WHO Grade III olarak değerlendirildi. Burada ekstra aksiyal yerleşimli ve anaplastik histomorfolojili ependimoma tanısı alan bir olgu güncel literatür ışığında tartışılacaktır.
