Case Report and Review of the Literature: Ischemic Stroke in Dengue Virus Infection

Dengue continues to pose a global health challenge, particularly in tropical and subtropical areas. Dengue can impact various organs, including the central nervous system, and can cause various neurological symptoms, although stroke is an uncommon complication. Among strokes, ischemic stroke is very uncommon in dengue. A 27-year-old unmarried female was referred to our institution with 8 days of fever and myalgia, 5 days of vomiting, and 3 days of altered sensorium. Small-sized bilateral pupils reacted slowly to light. Chest auscultation revealed diffuse coarse crepitation. Poor general condition and labored breathing led to intensive care unit transfer and intubation. Her contrast-enhanced brain magnetic resonance image showed chronic pontine infarction. She was diagnosed with dengue fever (NS1Ag positive) complicated by bilateral pontine infarction. After a long course of illness, she was finally discharged to home in good recovery status. Clinicians need to be aware of the uncommon dengue presentation of stroke. Treatment is supportive with variable outcomes.
