Graves’ Disease After Prolonged Immune Checkpoint Inhibitor Therapy
摘要
This is a case with preexisting hypothyroidism, who developed new-onset thyrotoxicosis after an extended period of receiving pembrolizumab for her cancer. This was associated with development of a goiter, worsening hyperthyroidism, and positive TSH receptor antibodies, all consistent with a diagnosis of Graves’ disease. Despite an extended course of methimazole therapy, her Graves’ disease remained suboptimally controlled, prompting her surgical thyroidectomy as definitive treatment.
