Renal Dysplasia in a Norwegian Forest Cat

Aresu, L., R. Zanatta, et al. (2009). “Bilateral juvenile renal dysplasia in a Norwegian Forest Cat.” J Feline Med Surg 11(4): 326-9.

Renal dysplasia is a kidney malformation made up of disorganized development of renal parenchyma due to abnormal differentiation. This condition leads to chronic renal failure in young animals. In addition to cats, renal dysplastic lesions have been found in dogs, cattle, horses, sheep, and humans. Renal dysplasia can be diagnosed only by histological examination of biopsy samples. The dysplasia can be unilateral or bilateral. In this case of a 5-month old Norwegian Forest cat, where the disease was bilateral, renal failure was the ultimate result. Kittens can often be clinically normal for extended periods of time; however, most of clinical signs are seen before 2 years of age. Feline renal dysplasia has been reported in fetal infections with panleukopenia virus. There are no reports of familial origins in feline renal dysplastic lesions. [VT]
