Cerebellar Dural Arteriovenous Fistula Presenting with Hemorrhage: Diagnostic Imaging and Endovascular Management.

Abstract

We report the case of a 45-year-old man with a rare cerebellar dural arteriovenous fistula (dAVF) presenting with dizziness and gait imbalance. MRI revealed a hemorrhagic lesion compressing the fourth ventricle. Digital subtraction angiography confirmed a Borden Type III dAVF, which was successfully treated by balloon-assisted embolization using PHIL 25%. This case draws attention to the importance of early diagnosis and intervention in posterior fossa dAVFs. Teaching point: Cerebellar dAVFs, though rare, harbor a high risk of hemorrhage and require prompt imaging and endovascular treatment.
