We report a case of an ectopic thyroid tissue with chronic lymphocytic thyroiditis presenting as a painless right jugulodigastric neck mass, which on ultrasound, was thought to be an abnormal right jugulodigastric lymph node. Contrast-enhanced CT showed that the mass had similar enhancement to the normally located thyroid gland and was separate from it. Fine needle aspiration of the mass, performed twice, was non-diagnostic. Excision biopsy of this mass was performed and histopathology showed chronic lymphocytic thyroiditis. To our knowledge, this is the first case of chronic lymphocytic thyroiditis presenting as an isolated jugulodigastric mass.
