“…Numerous causes of haemobilia occurring in the liver are discussed in the literature such as primary liver cancer (Fisher and Creed, 1956) or aneurysm of the hepatic artery either communicating directly with the duct system (Kerr, Mensh and Gould, 1950) or causing a central apoplexy (Mackay and Page, 1959). Goulston (1956) reported a most interesting patient, whom I was privileged to observe, suffering from recurrent severe and eventually fatal gastro-intestinal haemorrhage the cause of which was found at autopsy to be a large central liver hydatid cyst containing clotted blood and fibrin and whose lumen communicated with several bile ducts.…”
