Appropriate treatment that aims to reduce the risk of intracranial bleeding and manage the patient’s symptoms requires a multidisciplinary approach.Case Presentation: The patient was a 62-year-old man who developed symptoms of progressive right-sided otalgia and tinnitus. Cross-sectional imaging revealed long-standing venous congestion with intracranial hemorrhage in the right parieto-occipital region. Moreover, cerebral angiography demonstrated multiple complex dAVFs at the right transverse sinus-sigmoid sinus (TS-SS) junction, right posterior condylar confluence (PCC), and torcula. Treatment consisted of one session of endovascular treatment, in which transarterial Onyx embolization was used to treat the dVAF at the right TS-SS junction, transvenous coil embolization for the dVAF at the right PCC, and particle embolization for both occipital arteries feeding the torcular dAVF. Postoperative improvement with favorable clinical outcomes was observed at the patient’s last follow-up visit.Conclusion: Multiple cranial dAVFs are an uncommon vascular lesion, which can present with unusual symptoms such as otalgia. Moreover, a single session of endovascular therapy can treat this lesion, ie, it can improve the patient’s symptoms and provide a beneficial long-term outcome.Keywords: dural arteriovenous fistula, condylar vein, endovascular, transvenous embolization, coils |
