Imaging of Lyme Neuroborreliosis: A Pictorial Review
Lyme neuroborreliosis is a common feature of Borrelia burgdorferi infection (as a neurological manifestation occurring in 10%–15% of all Lyme disease cases) and may involve any part of the nervous system, and its coverings, but usually manifests as lymphocytic meningitis, cranial neuritis, and/or radiculoneuritis. This review describes the imaging findings in Lyme neuroborreliosis: the focal point is on the manifestations of involvement visible on brain and spine imaging.
Clarification: Far more than 10-15% have neurological manifestations. They also show “typical” EM rashes when many rashes are atypical: https://madisonarealymesupportgroup.com/2020/07/18/misdiagnosis-of-lyme-caused-rash-can-have-potentially-fatal-consequences/
The findings report the appearance of nonspecific lesions with inflammation as well as lymphocytic pleocytosis in cerebrospinal fluid (CSF).
It is possible that LNB may also mimic atypical dementia and normal pressure hydrocephalus.
