A Chinese woman in her 20s presented with a right lower neck swelling that appeared intermittently, especially during swallowing and coughing. She first noticed the swelling when she was aged 17 years. At that time, a barium swallow test result was normal, and dynamic ultrasonography of her neck showed transient dilation of her right internal jugular vein.
Ten years later, she returned with the same complaint, but did not report any pain or increase in its size. She had no difficulty breathing or swallowing, and no globus sensation. On examination there was no neck mass at rest. However, a soft, fusiform, and compressible swelling appeared in the right anterior triangle during the Valsalva maneuver. The swelling was even more prominent on swallowing, measuring 3 × 5 cm (Figure 1). Her nasoendoscopy results were unremarkable.
