Central nervous system infections are one of the common causes of stroke in developing
countries. Stroke after dengue is uncommon.
A total of 1148 dengue cases were seen in a tertiary referral hospital during the
epidemic from September to November 2008. We present 3 patients who had stroke caused
by dengue. The first patient was a 45-year-old woman with dengue hemorrhagic fever
who developed sudden right arm and leg weakness. Magnetic resonance imaging (MRI)
revealed multiple hemorrhagic foci in the left parietal and temporal lobes. The second
patient was a 35-year-old man who developed fever that was followed by altered sensorium
and quadriparesis. MRI showed bilateral cerebellar hemorrhages with edema, obstructive
hydrocephalus, and multiple watershed infarcts. The third patient was a 70-year-old
woman who presented with giddiness for 2 days followed by sudden weakness of the left
side of the body. She developed fever after admission. MRI showed infarct in the right
parietal lobe. All the patients had low platelet count and one patient died.
Dengue might be an important cause of stroke in epidemic regions when patients present
with fever, focal neurologic deficits, and encephalopathy.
