In a student course of gross anatomy dissection at Kanagawa Dental University in 2009, we found an extremely rare case of the coexistence of the postaortic left brachiocephalic vein with the postaortic left renal vein of a 73-year-old Japanese male cadaver. The left brachiocephalic vein passes behind the ascending aorta and connects with the right brachiocephalic vein, and the left renal vein passes behind the abdominal aorta. These two anomalous cases mentioned above have been reported respectively. There have been few reports discussing coexistence of the postaortic left brachiocephalic vein with the postaortic left renal vein. We discuss the anatomical and embryological aspect of this anomaly with reference in the literature.
