( Ciceri E.F., 2001) Occlusion of giant serpentine aneurysm with the carrying artery, complicated by infarction in the region of the left PCA.
  • Axial MRIs (T2) are indicative of giant serpentine aneurysm of P2/P3 segments of PCA.
  • Vertebral angiography, Towne view: serpentine aneurysm of the left PCA with involvement of P2 and P3.
  • Control vertebral angiography, Towne view: obliteration of aneurysm with the carrying artery; retrograde filling of cortical branches of PCA via anastomoses (an arrow).
  • Control MRI: acute infarction in a zone of autonomous blood supply in the region of the left PCA.
