A 66-year-old woman presented with acute thromboembolic stroke related to a large left cavernous carotid aneurysm. A, DSA in a lateral projection, after stent implantation, does not clearly depict the stent or its relationship to the host artery and aneurysm. B and C, Contrast-enhanced CBCT in projections longitudinal (5.0-mm MIP, B) and cross-sectional (2.5-mm MIP, C) to the stent shows the complex nature of the fusiform aneurysm, its intradural extension (arrow), and the apposition of the stent within the host artery. D, The operator can clearly evaluate the newly established vessel boundary and the remaining aneurysmal component, which was subsequently embolized.
