ABSTRACT
A 40-year-old woman with a history of Graves' disease status postorbital decompression for severe ophthalmopathy underwent total thyroidectomy by a high volume thyroid surgeon in July 2013 with a benign final pathology. Eight months later, she presented with a mass on the right anterior neck that showed minimal growth over time. Her thyroid stimulating immunoglobulin and thyroid-stimulating hormone receptor antibody levels were consistently elevated and increasing. She underwent removal of the neck mass in September 2016. Final pathology showed benign thyroid tissue with diffuse hyperplasia and lymphoid follicles, consistent with Graves' disease. We present an unusual recurrence of Graves' disease post-total thyroidectomy that recurred secondary to ectopic thyroid tissue in the right upper anterior neck deep to the strap muscles.
