1 Moyamoya disease with occlusion of bilateral vertebral arteries and the basilar artery fed by the collateral vessels of vertebral arteries: A rare case report  Xiaofeng Deng, Dong Zhang, Yan Zhang, Rong Wang, Bo Wang, Jizong Zhao  Journal of Clinical Neuroscience  Volume 42, Pages (August 2017) DOI: /j.jocn Copyright © 2017 Elsevier Ltd Terms and Conditions

2 Fig. 1 7.0-T axial T2-weighted brain MR images demonstrated infarction in left frontal lobe (A), numerous flow voids in sylvian cistern, interpeduncular cistern and quadrigeminal cistern (B, C), and an enlarged right PCoA (B, C, white arrows). 3.0-T T2-weighted MR images also detected the infarction (D) and flow voids around cerebral peduncles (E, F), but the images were unclear, especially in the imaging of microvessels.

3 Fig. 2 3.0-T sagittal T1- (A, C) and T2-weighted (B, D) cervical MR images showed tortuous and dilated vascular flow voids (white arrows) around the spinal cord and the ventral surface of the medulla oblongata.

4 Fig. 3 DSA images of bilateral carotid arteries in anteroposterior view showed occlusion at the end of the ICAs with moyamoya vessels at the skull base (A, B). Lateral view of bilateral ECAs suggested cerebral blood supply was partially compensated by the bilateral ECAs (C, D). Angiograms of VAs demonstrated occlusion at their terminal portions (black arrows, E–H). Tortuous and dilated collateral arteries arising from cervical segment of bilateral VAs fed the BA.
