Brain CT and MRI images. Representative images from a patient admitted to the First Hospital of Jilin University (Changchun, China) in May 2015 presenting with multiple dural arteriovenous fistulas are shown. All images were reproduced with the consent of the patient. (A and B) CT detected multiple high-density lesions that were considered as calcification lesions in the (A) lateral ventricle and (B) tentorium (white arrows). (C and D) Axial MRI of T2 weighted images identified dilated vessels in the (C) lateral ventricle and (D) brain surface (white arrows); (E) axial MRI of a fluid-attenuated inversion recovery image identified no infarction; (F) axial MRI of a diffusion-weighted image also identified no infarction. CT, computed tomography; MRI, magnetic resonance imaging.

In Fig. 1A and B, typical images of MDAVF imaging with brain CT are presented. In Fig. 1C-F, typical images of MDAVF detection by brain MRI are presented.
DSA images from the same patient in Fig. 1. (A) DSA of the left internal carotid artery detected direct arteriovenous shunts that were considered MDAVFs around the superior sagittal sinus and lateral sinus (white arrows); (B-D) DSA identified that these MDAVFs had feeding arteries from the (B) left external carotid artery, (C) right internal carotid artery and (D) right external carotid artery; (E and F) DSA identified that the DAVF in the lateral sinus had feeding arteries from the vertebral arteries. R and L denote the right and left sides. DSA, digital subtraction angiography; MDAVF, multiple dural arteriovenous fistula.
