Abstract:
The most frequently reported neurological complication of a wasp sting is ischemic stroke. We
treated a patient with wasp sting with unusual complications. A 52-year-old man was hospitalized
for anaphylactic shock after multiple wasp stings. Although the patient recovered consciousness
after 2 days, he had global aphasia and right hemiparesis. Brain magnetic resonance imaging and
angiography revealed high-intensity signals in the left basal ganglia and cerebral cortex and stenosis
of the left middle cerebral artery. After 2 days, the middle cerebral artery stenosis improved. After 5
days, diffusion-weighted imaging showed an enlarged lesion in the left frontal cortex. The infarct in
this case was due to a predominantly unilateral vasoconstrictive hypoxic brain injury from wasp stings.
