A 59-year-old woman presented with a 6-month history of a painless sensation of mild airway compression and a right-sided neck mass.
Contrast-enhanced computed tomography demonstrated a well-circumscribed,
right-sided, level IV nonenhancing mass (Figure 1) and a smaller mass abutting the thyroid gland (not shown). A diagnosis of branchial cleft cyst was made, and the patient underwent excision and thyroid biopsy. The pathology report identified a well-differentiated squamous cell carcinoma, and the thyroid specimen was noted to have squamous metaplasia. The patient was subsequently referred for evaluation and definitive management.
