Recent advances in ultrasound imaging allow visualization of the cervical part of the thoracic duct. In Panel A and Video 1, ultrasound imaging conducted to evaluate the thyroid of a 65-year-old man shows the thoracic duct (the central tubular structure) entering the venous angle between the jugular vein and the vertebral vein on the left side of the neck.
