Introduction: Acute and reversible parkinsonism is usually described after massive ingestion of organophosphate insecticides whereas acute intoxications occurring after pesticide spraying are rare.
Case report: We report one case of atypical parkinsonian disorder following repeated spraying with an aerosol insecticide containing pyrethre and organophosphate. This patient had a daily massive dermal and respiratory exposure to these pesticides for 10 years. Cerebral MRI was normal. DAT-scan showed a presynaptic loss of function.
Conclusion: Pesticides are suspected to be one risk factor responsible for parkinsonism. The present case supports this environmental hypothesis.
