Abstract

A five-month old female Great Dane with a history of depression and convulsion was submitted to the Pathology and Diagnosis Reference Division of National Veterinary Research and Quarantine service. The dog had ingested concentrated antifreeze and died 12 days after the sudden onset of clinical signs. Main gross lesion was limited to swollen kidneys with diffusely fine granularity on the cut surface. Principle microscopic lesions were focused on the kidneys including dilated Bowman’s space, thickened glomerular basement membrane, many light yellowish crystals, and proteinaceous casts in some tubules. Some neutrophils and lymphocytes were focally infiltrated in interstitium of the cortex and medulla. Crystals were angular or quite irregular in shape and arranged in sheave or rosette form. Under polarized light, the crystals were birefringent, which is typical of calcium oxalate crystals. Crystals were more concentrated in the cortex than in the medulla. A few crystals were also observed in the small blood vessels of the brain. Based upon the history of ingestion of antifreeze and the identification of calcium oxalate crystals in the tissue sections of the kidney and brain, this case was diagnosed as ethylene glycol toxicosis in a dog.
