Meyenburg complexes of the liver and bile cysts as a consequence of hepatic ischemia.

Meyenburg complexes and simple bile cysts are described in a patient having polyarteritis nodosa with involvement of the intrahepatic arterial tree. Similar lesions are found in the liver of monkeys subjected to experimental occlusion of the peripheral hepatic arterial tree. It is proposed that a pathogenetic mechanism conducive to the formation of Meyenburg complexes may be hepatic ischemia.
