SAT-369 Marine-Lenhart Syndrome: Case Report

Marine-Lenhart syndrome (MLS) is a rare condition characterized by the coexistence of Graves' disease and hyperfunctioning adenomas. This case report details a 46-year-old female with MLS, presenting with symptoms such as neck swelling, hair loss, and hyperthyroid indicators. Treatment involved thiamazole, propranolol, and minimally invasive procedures including percutaneous ablation and intrathyroidal dexamethasone administration. The patient achieved euthyroidism and a 58% reduction in nodule size. The report highlights the rarity of MLS and suggests that minimally invasive techniques, combined with antithyroid medications, can effectively manage the condition.
