We are reporting a surgical case of an unruptured fusiform aneurysm located on the A2 segment of the left anterior cerebral artery. The patient is a 49-year-old female who presented with nuchal pain. The presence of an anterior communicating artery (AcoA) aneurysm was suspected after analysis with MRI and MRA investigation. The left carotid angiogram revealed a 1 cm saccular aneurysm located on the AcoA portion of the artery. However, the 3D-CTA showed the presence of a left A2 segment fusiform aneurysm near the AcoA. The patient was operated on via left pterional approach. Two angled fenestrated clips were applied to the aneurysm so as to reconstruct the A2 segment. The postoperative course was uneventful, and the aneurysm was not visible in a subsequent angiogram. Thus, 3D-CTA has been shown to be useful in identifying an extremely rare case of an A2 segment fusiform aneurysm.
