Dengue fever presenting as acute cerebellar ataxia: Case report and literature review

Arthur Cesário de Holanda et al. J Neurovirol. 2022 Jun.

Abstract

Dengue fever has been associated with several neurological complications, cerebellar involvement being among the rarest of them. Here, we describe the case of a 70-year-old female who presented a cerebellar syndrome during the first day of an arboviral infection, posteriorly confirmed as dengue fever. Among the seven other cases in which the relationship between dengue virus and ataxia was reported, only in one cerebellar presentation occurred as early. Onset, course, and prognosis, as well as the adequate investigation and management of these patients, are discussed. While the disease pattern is not better characterized by future studies, differential diagnosis and close follow-up are essential tools for guaranteeing good outcomes.
