Nonketotik Hiperglisemide Görüntüleme Bulguları

Öz

Globus pallidus ve putamen, beyindeki metabolik değişikliklere duyarlı hipervasküler yapılardır. Nonketotik hipergliseminin değerlendirilmesinde ve görüntüleme bulguları ile ayırıcı tanıda kontrastsız beyin bilgisayarlı tomografide (BBT) globus pallidus ve nukleus kaudatus da genellikle simetrik ve bilateral ancak nadiren tek taraflı hiperatenüasyon ve T1 ağırlıklı manyetik rezonans görüntülerde (MRG) bu alanlarda hiperintensite artışı izlenmektedir. Bu yazıda acil servise kore olarak tanımlanan kontrolsüz hareketlerle başvuran diyabetik hastaların görüntüleme bulgularını sunmayı amaçladık.

Imaging Findings of Nonketotic Hyperglycemia

Öz

The globus pallidus and putamen are highly vascular structures, because of that, they are more sensitive to the metabolic changes in the brain. In the evaluation of nonketotic hyperglycemia and differential diagnosis with imaging findings is in the globus pallidus and nucleus caudatus usually symmetrically and bilaterally but rarely unilaterally hyperattenuating on non-enhanced computed tomography (NECT) and hyperintensity on T1-weighted magnetic resonance images (MRI) have been reported. In this report, we aimed to present poorly controlled diabetic patients that have been admitted to the emergency service with uncontrolled movements defined as chorea.
