Psilocybe mushrooms are consumed for their hallucinogenic properties. Fortunately, there are relatively few adverse effects associated with their consumption. This is the first reported case of acute kidney injury (AKI) secondary to confirmed ingestion of Psilocybe cubensis mushroom.

A 15-year-old male developed symptomatic AKI 36 h post-ingestion of Psilocybe cubensis mushrooms. He was admitted to hospital with hypertension, nausea and abdominal pain and a creatinine of 450 mmol/L. A sample of the crop of mushrooms was confirmed by mass spectrometry to contain psilocin. On day 5 post-admission, he was discharged home. Outpatient follow-up confirmed complete resolution of his renal function.
