[Acute Kidney Injury Caused by Orellanic Syndrome: Case Report].

Orellanic syndrome is caused by fungi of the Cortinarius orellanus and speciosissimus (Europe) species, Cortinarius fluorescens (South America), and Cortinarius rainierensis (North America). Orellanic syndrome is characterized by initially nonspecific symptoms such as muscle and abdominal pain, and a metallic taste sensation in the mouth. After a few days, more specific symptoms appear, such as intense thirst, headache, chills without fever, and anorexia, followed by a phase of polyuria and then of oligoanuria. Renal failure occurs in 70% of cases and is often irreversible. The clinical case involves a 52-year-old man who developed acute renal failure from Orellanic syndrome, necessitating hemodialysis.
