Abstract：
Posterior reversible encephalopathy syndrome (PRES) can develop in patients following exposure to multiple triggers, including blood pressure fluctuations, kidney diseases, immunosuppressive agents, chemotherapy, or autoimmune disorders. However, to the best of our knowledge, the development of PRES secondary to food poisoning has not been previously reported, especially in a pediatric patient. Here, we report a 13-year-old boy who presented with PRES following the consumption of palmatum (a chicken feet dish). The patient presented with headache, vomiting, and altered consciousness. Neuroimaging findings revealed white matter hyperintensities in a bilateral, symmetrical, and parieto-occipital pattern. The patient was diagnosed with PRES and was managed with fluid expansion and a short-term mannitol regimen (1 g/kg every 12 hours for 3 days). Neuroimaging findings returned to normal at 8 days after admission. Food poisoning may therefore be a new possible trigger for PRES. A timely PRES diagnosis is recommended to prevent possible central nervous system complications.
