We report two cases with internal carotid artery (ICA) aneurysms, in which fusion image effectively indicated the anatomical variations of the antenor choroidal artery (AchoA) Fusion image was obtained using fusion application software (Integrated Registration, Advantage Workstation VS4, GE Healthcare). When the artery passed through the choroidal fissure, it was diagnosed as AchoA Case 1 had an aneurysm at the left ICA Left internal carotid angiography (ICAG) showed that an artery arising from the aneurysmal neck supplied the medial occipital lobe Fusion image showed that this artery had a branch passing through the choroidal fissure, which was diagnosed as hyperplastic AchoA Case 2 had an aneurysm at the supraclinoid segment of the right ICA AchoA or postenor communicating artery (PcomA) were not detected by the right ICAG Fusion image obtained from 3D vertebral angiography (VAG) and MRI showed that the right AchoA arose from the nght PcomA Fusion image obtained from the right ICAG and the left VAG suggested that the aneurysm was located on the ICA where the PcomA regressed. Fusion image is an effective tool for assessing anatomical vanations of AchoA The present method is simple and quick for obtaining a fusion image that can be used in a real-time clinical setting.
