We are presenting a case of a 55-year-old Caucasian female who presented with acute kidney injury requiring hemodialysis. Her native kidney biopsy showed extensive crystals in both the cortex and medulla, morphologically consistent with calcium oxalate crystals. The etiology was attributed to vitamin C-induced kidney hyperoxaluria. She has remained hemodialysis dependent for more than three months since the initial presentation, establishing a diagnosis of end-stage kidney disease.
Keywords: acute kidney injury; end stage kidney disease; hyperoxaluria; oxalosis; vitamin c toxicity.
