The human brain is divided into four lobes by four major sulci including the lateral, central, parieto-occipital, and calcarine sulci. These sulci were used as landmarks for the brain's higher functional areas and during brain surgical entrances. According to the previous reports the variants of these main sulci were founded. The current study aimed to show a case report about the variant of the main sulci for the human brain. This study was managed on the plastinated human brain samples during the dissection room training for medical students in the medical college at Najran University in Saudi Arabia. Our study showed that there are abnormalities in the direction and distributions of the main sulci of the brain cortex a rare case. Therefore, our findings can help surgeons to understand the sulci course and their subdivision areas on the cerebral cortex to do their procedures.
