Patient
male, 55 year(s)
 
 
  • Figure 1
    Axial SE T1-weighted MR image of the brain

    shows acute bleeding in the centrum semiovale of the left hemisphere.

     
    Area of Interest: unknown; Imaging Technique: Axial SE T1-weighted MR image of the brain;
     
     
  • Figure 2
    Axial MIP-MR angiography of the brain

    demonstrates an occluded ICA, anterior (ACA) and middle cerebral artery (MCA) on the right side. Occlusion of the left ACA and MCA, and intense signal of both posterior cerebral arteries (PCA) are seen. Some...

  • Figure 3
    Oblique projection
     

    Intra-arterial DSA of the brain includes left common carotid artery (CCA) arteriography, oblique projection which showed occlusion of the proximal ACA and MCA. Additional abnormal vascular network in the region of...

     
    Area of Interest: unknown; Imaging Technique: Oblique projection;

    Right CCA-arteriography, AP projection, demonstrates total occlusion of the ICA and its intracranial main branches. Transdural anastomosis from the superficial temporal artery to the cortex is noted.

     
    Area of Interest: unknown; Imaging Technique: Oblique projection;

    Left vertebral arteriography, lateral projection, visualizes enlarged branches of the PCA sending leptomeningeal collateral vessels to the ACA and MCA territories. A marked basal vascular network is seen. Based on the...

demonstrates an occluded ICA, anterior (ACA) and middle cerebral artery (MCA) on the right side. Occlusion of the left ACA and MCA, and intense signal of both posterior cerebral arteries (PCA) are seen. Some additional vessels at the level of the proximal PCA-portions are also visible.
 
Intra-arterial DSA of the brain includes left common carotid artery (CCA) arteriography, oblique projection which showed occlusion of the proximal ACA and MCA. Additional abnormal vascular network in the region of the basal ganglia is seen.
 
Right CCA-arteriography, AP projection, demonstrates total occlusion of the ICA and its intracranial main branches. Transdural anastomosis from the superficial temporal artery to the cortex is noted.
 
Left vertebral arteriography, lateral projection, visualizes enlarged branches of the PCA sending leptomeningeal collateral vessels to the ACA and MCA territories. A marked basal vascular network is seen. Based on the clinical and radiological features, the diagnosis of Moyamoya disease (MD) was made.
