Bannwarth syndrome (BWS), an infrequent manifestation of neuroinvasive Lyme disease (LD) characterized by radiculopathy, neuropathy, and lymphocytic pleocytosis, is more commonly documented in Europe than North America. Here, we describe a cluster of 5 neuroinvasive LD cases with BWS in the upper Midwest United States between July and August 2017.
