Figure 3. Neuroimaging.

Figure 3

(A) Restricted diffusion involving the medial aspect of the right cerebral peduncle. (B–F) Axial (B, C), coronal (D, showing right CNIII nerve), and sagittal (E, right CNIII nerve; F, left CNIII nerve) 3D-CISS MRI showing the right SCA (arrowhead) indenting the inferior and medial part of the CNIII nerve (arrow) in the cistern space, resulting in nerve extension and deviation. HRMR-VWI showed stenosis and a plaque in the origin of right PCA (G–H, arrow). 3D-CISS = 3-dimensional constructive interference in steady state; CNIII = third cranial nerve; HRMR-VWI = high-resolution magnetic resonance vessel wall imaging; PCA = posterior cerebral artery.
