Figures

  • Figure 1.
    Figure 1.

    Right internal carotid artery injection shows distal interior carotid artery occlusion with prominent lenticulostriate and leptomeningeal collaterals (white arrow) consistent with the characteristic “puff of smoke” appearance of moyamoya. Also shown are distal pericallosal (anterior cerebral artery) branches and distal middle cerebral artery branches (thick black arrows) filling via the enlarged posterior communicating artery (thin black arrow).

  • Figure 2.
    Figure 2.

    Right external carotid injection in (A) anteroposterior film and (B) lateral film. In both images, an enlarged middle meningeal artery (white arrows) can be observed crossing the midline and providing extracranial-to-intracranial collaterals to bilateral anterior cerebral artery territories (black arrows).

  • Figure 3.
    Figure 3.

    Left internal carotid injection shows high-grade interior carotid artery stenosis and A1 and M1 occlusion with lenticulostriate collaterals (white arrow) consistent with moyamoya. Additionally, an enlarged ophthalmic artery provides collaterals to the anterior frontal branches of the anterior cerebral artery (black arrow).
