Background: As part of a study of the microsurgical anatomy of the pericallosal artery, we describe one brain with three unusual anatomic variants. %26lt;br%26gt;Methods: From the autopsy findings of a 45-year-old female, we extracted the brain. All the arterial blood vessels were washed with saline solution to be injected afterwards with red latex. The brain was then immersed in 10% formalin for 2 months. Finally, we dissected and measured the internal carotid artery segments using a digital Vernier caliper under a Carl Zeiss OPMI surgical microscope (magnification x6 to x40). %26lt;br%26gt;Results: Weight of the brain was 1250 g and three rare anatomic variants were found: 1) right accessory middle cerebral artery (MCA-r), 2) right bihemispheric anterior cerebral artery (ACABihem-r), 3) median artery of the corpus callosum (MACC). %26lt;br%26gt;Conclusion: Association of the anatomic variations described previously is inconsistent; furthermore, their appearance in a single case is rare.
