Rare occurrence of sagittal sinus thrombosis and haemorrhagic infarction with dengue fever; jumping from traditional symptoms to lethal neurological consequences

Dengue virus (DENV) is an RNA virus transmitted by Aides mosquito causing dengue fever. There is growing recognition of neurological symptoms associated with DENV infection, some of which might be lethal if left untreated. Case reports describing sagittal sinus thrombosis, as a serious neurologic consequence of dengue infection, are rare. It is still unknown how often sagittal sinus thrombosis occurs and what variables increase the risk in dengue patients.
