  Online Figure 1: A 68-year-old woman with episodes of dysphasia. A and B, CT scan (A) and MR image (B) demonstrate a serpentine partially thrombosed aneurysm of the left middle cerebral artery. C and D, Lateral (C) and frontal (D) views of the 3D angiogram show a fusiform dilated aneurysm lumen. E and F, Frontal skull radiograph (E) and angiogram (F) after internal coil trapping.
  
  Online Figure 2: A 51-year-old woman with progressive frontal syndrome. A, MR image demonstrates a 5-cm giant serpentine aneurysm with surrounding edema. B, Frontal view of left internal carotid angiography shows the aneurysm originating from the left anterior cerebral artery with a tortuous luminal channel. Flow direction and sequence are indicated by numbered arrows. C, Microcatheter inside the luminal channel. From this point, glue was injected. D, Glue cast after embolization. E, Preoperative angiogram 9 months later demonstrates stable occlusion of the luminal channel. F, Preoperative MR image with resolution of perifocal edema. Note the small middle cerebral artery infarction that developed 6 months after embolization from an unknown source.
