Ethylene glycol poisoning is commonly associated with which findings?

• A. Severe AGMA with AKI and calcium oxalate nephrolithiasis
• B. Optic neuropathy and vision loss
• C. Visual disturbances
• D. Hyperkalemia

Answer: (B)

Ethylene glycol poisoning is best recognized by a severe anion gap metabolic acidosis with an elevated osmolar gap and acute kidney injury from calcium oxalate deposition. As glycolate and oxalate accumulate, calcium oxalate crystals form in the renal tubules, sometimes leading to nephrolithiasis. Optic neuropathy and vision loss are more typical of methanol poisoning, not ethylene glycol. Hyperkalemia is not a defining feature. So the classic accompanying findings are the severe metabolic acidosis with kidney injury and calcium oxalate involvement.
