초록
It is important for the diagnosis of Lambert-Eaton myasthenic syndrome (LEMS) to confirm the incremental response at high-rate stimulation or after brief exercise in the repetitive nerve stimulation (RNS) test. Therefore, it may be difficult to diagnose LEMS if the RNS test is normal initially. We report a patient with LEMS whose diagnosis was delayed due to normal RNS findings. We believe that anti-P/Q-type voltage-gated calcium channel antibody testing is crucial in the diagnosis of LEMS.
