A Rare Case of Thyrohyoid Syndrome following Total Thyroidectomy due to Metastatic Strumi Ovari

Introduction

•Thyrohyoid Syndrome or lateral thyrohyoid ligament syndrome is an uncommon inflammatory condition of the ligament and surrounding tissues.

Case Description

•44 yo female with rheumatoid arthritis and s/p total thyroidectomy in 12/2023 with completion of radioactive iodine therapy after biopsy confirmed metastatic struma ovari with well differentiated follicular thyroid carcinoma presented to pain clinic endorsing unilateral anterior neck pain.

•On physical exam, she was tender with deep palpation of the right superior cornu of the thyroid cartilage. Tentative plan for US-guided corticosteroid injection with anesthetic targeting the lateral thyrohyoid ligament was discussed.

Discussion

•The patient in this case presented to the clinic with a unique medical history but typical presentation of most patients who have been diagnosed with lateral thyrohyoid ligament syndrome.

•It is an inflammatory condition, likely the result from an inciting trauma or due to overuse from excessive swallowing or voice projection.

•NSAIDs and a short course of oral steroids are the first line management for this condition.

•The most effective treatment with is injection of local anesthetic and steroids.

Conclusion

•There is a paucity of literature documenting lateral thyrohyoid ligament syndrome.

Thyrohyoid Syndrome is an uncommon inflammatory condition due to overuse/trauma of the lateral thyrohyoid ligament that is conservatively treated with NSAIDs or local anesthetic/steroids.
