[Ischemic stroke in dengue: Are we facing an immunomediated response? A case report].

Neurological manifestations in dengue infection are atypical; even more so are cases of stroke, which have only been reported rarely. We present the case of a 41-year-old male patient who developed focal neurological deficit during his dengue infection. The patient had no known comorbidities. He presented with fever, headache, myalgia, and biochemical results showed thrombocytopenia. A plain brain CT scan did not reveal any lesions, leading to the diagnosis of ischemic stroke in the context of dengue infection. He showed improvement in neurological symptoms correlated with increasing platelet counts. Such association has been described in other reports of ischemic stroke due to dengue, possibly explained by immunomediated effects leading to a vasculitic condition. The aim of this work is to contribute to the existing evidence on this entity.
