A 36-year-old man was admitted to a hospital in a stupor with a history of six days of oliguria after a period of heavy alcohol intake. He complained of headache and of tenderness bilaterally in the costophrenic angles. He underwent dialysis by means of a twin-coil kidney twice, with evidence of improvement each time. He remained lethargic, however, continued to void less than 20 ml. of urine per day, and died in coma on the 17th day of oliguria. Autopsy findings included the presence of birefringent crystals of calcium oxalate in many of the kidney tubules; this is diagnostic of ethylene glycol intoxication.
