Development of Graves orbitopathy after thyroidectomy for thyroid cancer.

We present a case of a 76-year-old female with a history of papillary thyroid cancer treated with a total thyroidectomy, central neck dissection, and radioactive iodine (radioactive iodine) in 2006.

Sixteen years later, she was found to have lung metastases and underwent a treatment dose of radioactive iodine.

Given no improvement in her thyroglobulin levels, she underwent a third dose of radioactive iodine.

One week following this, she presented with new ophthalmalgia, conjunctival injection, and binocular diagonal diplopia.
