Cerebral Venous Sinus Thrombosis in a Child with Dengue Fever: A Rare Case Report

Abstract: Background: Dengue fever is a prevalent arboviral infection in tropical countries, often presenting as a nonspecific febrile illness. Neurological complications, although rare, can significantly impact morbidity. Among these, cerebral venous sinus thrombosis (CVST) is a life-threatening but underrecognized entity. Case Presentation: We describe a case of an 11-year-old female who presented with classical symptoms of dengue fever, which progressed to altered mental status and visual disturbances. Her investigations showed thrombocytopenia and positive dengue serology. A detailed neurological examination shown neck stiffness and positive Kernig?s sign. MRI with venogram confirmed CVST involving the superior sagittal sinus, right sigmoid, and bilateral transverse sinuses. With appropriate anticoagulation therapy and supportive care, the patient showed marked improvement. Conclusion: This case emphasizes the need for heightened clinical suspicion of CVST in pediatric dengue cases presenting with neurological symptoms. Early neuroimaging and anticoagulation can be lifesaving.
