Manifestation of Marine Lenhart Syndrome after failed Radioactive Iodine therapy

Abstract

Marine Lenhart Syndrome (MLS) is caused by a coexistence of active thyroid nodules and Graves’ disease1. Here, we present a case of hyperthyroidism characterized by the presence of stimulating TSH receptor antibodies, unsuccessful radioactive iodine ablation, ultimately requiring Methimazole followed by thyroidectomy. We review the current literature.
