delphian node adenopathy

The Delphian (prelaryngeal/precricoid) lymph node (often shortened to Delphian node) is one of the cervical lymph node groups that comprise level VI cervical lymph nodes and is not routinely excised in radical neck dissections.

Gross anatomy

It is located between the cricothyroid muscles, above the thyroid isthmus, lying directly anterior to the cricothyroid membrane . It receives lymph from the thyroid gland (mainly the upper poles) and the larynx .

History and etymology

The Delphian node gains its name from the Oracle of Delphi, whose prophecy, in this case, would be of an unpleasant death secondary to laryngeal cancer.

Related pathology

Involvement of this node can be as a result of diffuse nodal involvement in head and neck squamous cell carcinoma or in isolation from direct lymphatic spread of laryngeal cancer through the anterior commissure. Thyroid carcinomas may also involve this node, in which case it usually signifies disease spread to the central and lateral cervical lymph nodes .
