| Abstract: | Two examples of renal papillary necrosis in the tiger are described. The necrosis was characterised by large zones of liquefaction with minimal inflammation and was associated with pronouced scarring in the cortex. Both animals had been vomiting terminally and were severely dehydrated. It is suggested that papillary necrosis was precipitated by the reduced renal perfusion associated with dehydration in kidneys in which the medullary blood supply was already compromised by chronic cortical scarring. Comparisons are made between the lesions described in these tigers and those reported in the domestic cat, man and other domestic animals. |
