Dengue fever with encephalitis: An uncommon presentation of common illness

The dengue virus is a type of Flavivirus that causes dengue fever. It is mostly found in tropical and subtropical countries, with Southeast Asia bearing the brunt of the disease burden. The virus can affect a wide range of organ systems, and the disease can range from a mild flu-like illness to severe dengue hemorrhagic fever or dengue shock syndrome. We present a case of a 21-year-old female who presented with dengue fever with neurological manifestations. Findings from a brain MRI, electroencephalogram, CT scan, and some routine investigations were supported our diagnosis of dengue encephalitis. Conservative and supportive care was provided, including intravenous fluid therapy, antibiotics, antivirals, antiseizure medications, and corticosteroids. The patient's GCS gradually improved with treatment, and physical therapy was also provided. Treatment that is both effective and timely can reduce associated morbidity and result in complete recovery.
