Presumed primary and secondary hepatic copper accumulation in cats.

Objective: To determine signalments, clinical features, clinicopathologic variables, imaging findings, treatments, and survival time of cats with presumed primary copper-associated hepatopathy (PCH) and to determine quantitative measures and histologic characteristics of the accumulation and distribution of copper in liver samples of cats with presumed PCH, extrahepatic bile duct obstruction, chronic nonsuppurative cholangitis-cholangiohepatitis, and miscellaneous other hepatobiliary disorders and liver samples of cats without hepatobiliary disease.

Design: Retrospective cross-sectional study.

Animals: 100 cats with hepatobiliary disease (PCH [n = 11], extrahepatic bile duct obstruction [14], cholangitis-cholangiohepatitis [37], and miscellaneous hepatobiliary disorders [38]) and 14 cats without hepatobiliary disease.
