Parkinsonism after a wasp sting

Area of Science:

• Neurology
• Toxicology

Background:

• Insect stings, particularly from the Hymenoptera order, can cause diverse neurological complications.
• Parkinsonism is a neurological disorder characterized by tremors, rigidity, and bradykinesia.

Observation:

• A 49-year-old man developed parkinsonism following a wasp sting.
• His condition progressed to severe akinetic-rigid syndrome with basal ganglia destruction.
• Standard antiparkinsonian medications were ineffective.

Findings:

• The patient's symptoms stabilized and partially reversed with plasmapheresis, intravenous immunoglobulin, and azathioprine.
• Magnetic resonance imaging revealed significant basal ganglia destruction.
• Literature review indicates a need to consider Hymenoptera stings in extrapyramidal syndromes.

Implications:

• Hymenoptera stings represent a potential, albeit rare, cause of acute and chronic extrapyramidal syndromes.
• This case highlights the importance of considering insect stings in the differential diagnosis of parkinsonism.
• Novel therapeutic strategies involving immunomodulation may be effective in managing neurotoxic injuries from insect stings.
