Abstract
AbstractNeurological manifestations of dengue are increasingly seen, especially in endemic regions. The wide availability of cross sectional imaging has allowed radiological depiction ofCNSinvolvement in symptomatic patients. Classically, dengue was thought to be a nonneurotropic virus; however, increasing evidence is suggesting central nervous system involvement. A number of pathophysiologic mechanisms have been proposed to explain the development of the neurological symptoms seen. Although there is no specific neuroimaging feature at present, knowledge of its variable appearance may aid in treatment, prognostication, and follow up. In this article, we attempt to review, comprehensively, the spectrum of neuroimaging findings in dengue, viaCTandMRI. We also discuss some common pitfalls associated with this disease entity.
