A 69-year-old white man presented to the emergency department reporting 2 months of progressive bilateral lower extremity weakness, left facial weakness, and diplopia in the setting of a 20.4-kg weight loss over the previous 6 months and new-onset urinary incontinence. Two months prior he had undergone lumbar vertebra 3–sacra vertebra 1 lumbar laminectomies performed for symptomatic spinal stenosis. Despite this, his leg weakness worsened. He denied headaches, fevers, cough, risk factors for immunosuppression, or travel outside of the northwestern United States.
