Myocarditis and Myasthenia Gravis induced by Immune Checkpoint inhibitor
(ICI) in a patient with relapsed thymoma: a case report
A 55-year-old male cancer patient with ICI therapy (PD-1 antibody)
started to manifest myasthenia gravis (MG) symptoms, cardiac injury,
intermittent third-degree atrioventricular block, and ventricular pause
necessitating temporary cardiac pacing. Intravenous steroids and
immunoglobulin, pyridostigmine, and mycophenolate mofetil were
sequentially initiated and the above symptoms were gradually resolved.
