Ruptured Intracranial Mycotic Aneurysm in Infective Endocarditis: A Natural History
Figure 4
CT Cerebral angiogram showing a large fusiform aneurysm at the distal anterior cerebral artery (ACA). (a) Shaded Surface Display CT coronal view showing a large fusiform aneurysm at the distal segment of the ACA marked by the large arrow. Proximal ACA segments are marked by the smaller arrows. RIC: right internal carotid artery, LIC: left internal carotid artery, RMCA: right middle cerebral artery, LMCA-left middle cerebral artery, RACA and LACA are right and left anterior cerebral arteries, respectively. (b) Close-up coronal view of ACA mycotic aneurysm. (c) Additional sagital view of mycotic aneurysm. (d) CT Angiogram axial view, an arrow marks the location of the ruptured aneurysm adjacent to a large hemorrhagic lesion. (e) CT Angiogram sagital view demonstrating areas of intracerebral hemorrhage.
