The demonstration of a male, 55-year-old case. a The 3D RCA development of DSA shows the PComA aneurysm originating from the origin of the full-type PCA. White arrowhead shows the aneurysm. The triangle shows the origin of full PCA type from RCA system. b The vertebral development of DSA shows the missing of PCA. c The postoperative RCA development of DSA shows no image of the PCA after surgical clipping and the aneurysm is totally eliminated. The triangle shows the preoperative origin site of full PCA type from RCA system. d The postoperative vertebral development of DSA shows the missing of PCA and totally occlusion of the aneurysm for c. Five-pointed star indicates the titanium clips. e, f The postoperative CT scan show the infarction of right temporal and occipital lobe. The red ellipses demonstrate the ischemic low density. g, h The CT perfusion imaging (axial time to peak) shows the ischemia (red area) of right temporal and occipital lobe
