The entire course of the disease lasted about 10 mo. The autopsy revealed extensive fibrinoid necrosis in the liver, kidney, spleen, pancreas, lung, lymph nodes, and pleura. Particularly extensive fibrinoid necrosis in the portal tracts of the liver induced severe stenoses of the intrahepatic bile ducts, resulting in cholestasis in association with prominent liver injury. There were no findings indicating primary sclerosing cholangitis. The hepatic lesions in this case did not coincide with any known disease including collagen diseases. To clarify the cause of irregular stenoses of the intrahepatic biliary trees on cholangiographic findings, we postulate that some form of immunological derangement might be involved in pathogenesis of fibrinoid necrosis. However, the true etiology remains unknown.展开更多
