About 5 percent of aneurysms are on the pericallosal or distal anterior cerebral artery (DACA) and are associated with anomalous A2s, multiple aneurysms (50 percent), and AVMs.180 They are most common at the genu of the corpus callosum. These aneurysms are treacherous, deceptive, and require a carefully planned approach, which varies in angle of access according to the position of the aneurysm along the course of the distal anterior cerebral artery.181 The frontal interhemispheric route must be low enough to expose the parent A2 proximal to the aneurysm.182-183 The coronal interhemispheric transcallosal approach is preferred if the lesion is above the genu of the corpus callosum.184 Lesions inferior to the genu can be accessed through the corpus callosum so that A2 proximal to the aneurysm is controlled.
