A Rare Variant of Zuckerkandl Tubercle: Thyroid Ring

Zuckerkandl tubercles are posteromedial projections of normal thyroid gland with relations with important neck structures. In our case, we reported “Thyroid ring”, that is a ring configuration of the thyroid gland encasing the trachea and esophagus, without compression symptoms. Ring was formed by the elongated zuckerkandl tubercles, passing through the column between the esophagus and vertebral body and abutting each other at left posterolateral border of esophagus. Reporting of these relations and variations is important as it helps the operating surgeon in planning the approach to the procedure.
