Dengue infection can present as febrile illness with thrombocytopenia, dengue shock syndrome and dengue haemorrhagic fever. Neurological manifestation of dengue infection is more predominant in endemic region. Here, we report a case with unusual neurological presentation of dengue infection. A 16-year-old boy presented with fever for two week duration, headache and double vision involving left eye for two days. He had multiple erythematous rashes all over the body on 3rd day and treated conservatively. On examination he had bilateral papilloedema, left eye restricted abduction. His investigation revealed thrombocytopenia and positive dengue serology. His MRI brain with venogram showed bilateral transverse sinus thrombosis. Hence he was diagnosed as cerebral venous thrombosis due to dehydration with underlying dengue infection. He was hydrated and managed conservatively. On 3rd day his double vision started improving. His repeat MR Venogram was done after two week duration, which revealed recanalisation of bilateral transverse sinus.
