Ischemic Cerebellar Infarct During Recovery from Secondary Dengue Fever—A Case Report and Literature Review

Background: Dengue fever is a global health problem and is endemic in Singapore, with a high economic burden. Neurological manifestations of dengue fever, although rare, are being increasingly reported. Ischemic stroke as a complication of dengue fever has rarely been reported. Methods: This case report describes a case of ischemic cerebellar infarct during the recovery phase of secondary dengue fever with a review of similar cases previously described in the literature. Results: This is the first known case report of cerebellar ischemic stroke in Singapore following dengue fever, where Magnetic Resonance Angiography (MRA) demonstrated a possible occlusion or severe stenosis of a cerebral artery as the underlying pathophysiology of dengue-associated stroke. Dengue fever has been shown to increase the incidence of stroke. Conclusions: Physicians in dengue-endemic areas need to have a high index of suspicion to consider this diagnosis, especially in patients with dengue fever who present with neurologic deficits.
