Renal papillary necrosis was diagnosed during postmortem examination of a juvenile white-tailed deer (Odocoileus virginianus) from Oklahoma. The deer was surgically treated for a Salter Harris type II fracture of the proximal tibia of the left hind limb. The animal was administered multiple nonsteroidal anti-inflammatory drugs (NSAIDs), including meloxicam, flunixin meglumine, and ketoprofen for pain management. At postmortem examination, gross lesions included a proximal tibial Salter Harris type II fracture with an associated fibrinonecrotizing myositis and bilateral renal papillary necrosis. Histologically, the kidneys exhibited coagulation necrosis of the renal medulla and renal papilla, thrombosis of renal blood vessels, and interstitial medullary edema. The gross and microscopic lesion coupled with the clinical history of multiple NSAID administration suggests NSAID-induced renal papillary necrosis.
