A 65-year-old man who had been on hemodialysis for chronic renal failure was well until 7 days after ingestion of Pleurocybella porrigens (Sugihiratake) when he developed a loss of consciousness and status epilepticus of generalized tonic and clonic seizures. High fever and high CRP were followed and cerebrospinal fluids showed marked pleocytosis with polynuclear cell predominance. Brain MRI showed diffuse lesions in the basal ganglia and multiple ringed lesions in cerebral cortex. Glucocorticoid therapy was effective for clinical improvement. This case showed the presence of encephalitis -type of encephalopathy related to Pleurocybella porrigens (Sugihiratake).
