The purpose of this study was to expand our knowledge about anatomical variations of the origin, course and end of the sinus node (SN) artery. Herein I describe a rare postmortem corrosion casting finding, which concerns a unique and previously unreported case where the SN artery had an abnormal origin and course to the SN area. Although the patient was asymptomatic, knowledge of this anatomical variation, its possible involvement with invasive or surgical procedures and its clinical consequences should be considered.
