Cerebral Alveolar Echinococcus Mimicking Brain Tumor

Abstract

Cerebral alveolar echinococcosis is a rare infestation of Echinococcus accounting for only 1% of patients infected with this parasite. This disease is endemic in Turkey and it is particularly common in the eastern Anatolia region. A 33-yearold female patient presented with neurological symptoms to our hospital with neurological symptoms and she previously had diagnosis of liver echinococcus alveolaris. Imaging studies showed a mass lesion in cerebrum which was diagnosed as cerebral alveolar echinococcosis. In this report we discussed computed tomography (CT) and magnetic resonance imaging (MRI) findings of cerebral alveolar echinococcosis with emphasizing distinguishing imaging features of this disease from other cerebral mass lesions.

Beyin Tümörünü Taklit Eden Serebral Alveolar Ekinokok

Öz

Serebral alveolar hidatik hastalık Ekinokokok parazitinin nadir bir enfestasyonu olup bu parazitle enfekte olanların %1'inde görülür. Bu hastalık Türkiye'de endemik olup özellikle Doğu Anadolu'da daha sıktır. Daha önce karaciğer alveolar ekinokoku tanısı alan 33 yaşındaki bayan hasta hastanemize nörolojik semptomlarla başvurdu. Görüntüleme çalışmalarında beyinde alveolar ekinokok tanısını düşündüren kitle lezyonu saptadı. Bu sunumda serebral alveolar ekinokok hastalığının bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) bulgularını ve özellikle beyinde diğer kitle lezyonu oluşturan hastalıklardan ayırtedici görüntüleme özelliklerini tartıştık.
