Vertebrobaziler hipoplazi bulunan olguda unilateral vertebral arter diseksiyonuna bağlı beyin sapı enfarktının radyolojik bulguları

Vertebrobaziler sistemin konjenital hipoplazisi oldukça nadir görülen fakat özellikle genç erişkin hasta grubunda posterior sistem iskemi ya da enfarktına neden olabilecek önemli bir klinik durumdur. Genellikle semptomatik olduğunda tespit edilen bu hastalığın tanısında beyin bilgisayarlı tomografi (BT), manyetik rezonans görüntüleme (MRG) ve diffüzyon görüntüleme yöntemlerinden faydalanılır. Biz bu olguyu nadir görülen ve klinik olarak önemli sonuçları olan bu hastalığın radyolojik bulgularının bilinmesinin tanıya katkı sağlayacağı düşüncesiyle sunmaktayız.

Radiological findings of brain stem infarction due to unilateral vertebral artery dissection in a patient with vertebrobasilar hypoplasia

Congenital hypoplasia of the vertebrobasilar system is a very rare condition but it is an important clinical condition which may cause ischemia or infarction of the posterior system especially in young adult patients. Brain computed tomography (CT), magnetic resonance imaging (MRI), and diffusion imaging are used to diagnose of this disease which is usually detected when it is symptomatic. We present this case with the thought that knowing the radiological findings of this rare disease with clinically important results will contribute to the diagnosis.
