Osteodystrophia fibrosa secondary to a chronic renal failure in a dog. a case report

Abstract

A five year male Rottweiler was presented to the Small animal clinic of the Veterinary Teaching Hospital. University of Ibadan, being a referral from Lagos. Bilateral swelling and deformity of the skull bones were observed. Palpation revealed swollen gums and weak mobile teeth weak. Urination was frequent and the urine very clear. Haematology and blood chemistry revealed non-regenerative anaemia, mild leucopenia, hypocalcaemia, hyper-phosphataemia, high serum blood urea and creatinine, and hyper-bilirubinaemia. Treatment was instituted with dextrose saline to rehydrate the animal and correct electrolyte and metabolic disorders. The dog however died despite intervention. At post mortem, the carcass was found to be jaundiced, the premolars were mal-positioned. Calcification was visible on the lower jaw. Kidneys were small, firm, with many white specks on the cortical surface. A diagnosis of Uremic renal failure with Osteodystrophia fibrosa (renal rickets) was made. The possible causes and clinical implications of the condition were discussed.
