Liver hemorrhage due to idiopathic peliosis hepatis successfully treated with hepatic artery embolization

Abstract

Peliosis hepatis is an extremely rare condition that may cause fatal hepatic hemorrhage and liver failure. We report a case of liver hemorrhage due to idiopathic peliosis hepatis. A 60-year-old woman was admitted to our hospital with slight right hypochondriac pain. She went into hemorrhagic shock, and computed tomography (CT) showed multiple lowdensity areas in the right liver with massive subcapsular blood collection. Selective transfemoral arteriography of the celiac artery revealed no signs of vascular malformation or tumor stain, but showed signs of pooling in the right posterior segmental artery. The artery was embolized with particles of gelatin sponge, and hemostatic control was successful. Although peliosis hepatis is extremely rare, the diagnosis is significant because of its urgent clinical status, and transarterial embolization is a useful and minimally invasive procedure for liver hemorrhage due to peliosis hepatis.
