A middle‐aged man with lymphomatous meningitis developed acute cervical radiculopathy. Repetitive stimulation of an affected nerve revealed a “U‐Shaped” decrement. The decrement was absent 10 days later. We hypothesize that the decrement was secondary to simultaneous denervation of many motor units and disappeared as denervation became complete in those motor units.
