Haemorrhagic rupture of hepatic simple cysts.

Haemorrhagic rupture is a life-threatening complication of a hepatic simple cyst. A 63-year-old man presented with severe acute abdominal pain and a massive haemoperitoneum resulting from haemorrhagic rupture of a large hepatic cyst. The haemorrhagic rupture was aggravated by an overdose of vitamin K-antagonist treatment. CT scans revealed a large hepatic simple cyst. The patient was successfully treated conservatively with resuscitation, transfusion therapy and administration of coagulation agents. To date, there is no clear evidence regarding optimal treatment of haemorrhagic hepatic cyst rupture. The risk of recurrent bleeding from the haemorrhagic hepatic simple cyst, and the need for final treatment to avoid rebleeding either by percutaneous sclerotherapy, endovascular embolisation, surgical cyst resection, or surgical deroofing, is discussed. 2015 BMJ Publishing Group Ltd.
