Solitary Nonparasitic Cysts of the Liver

Solitary nonparasitic cysts of the liver occur with sufficient rarity to make this report of two cases of interest. In 1913, Boyd1collected thirty-four such cases reported in the medical literature, operation having been performed in each case. In 1923, John F. X. Jones2of Philadelphia observed another instance, and in an excellent review of the literature on the subject, found that the reported number of cases in which operation had been performed at that time aggregated sixty-one. Jones quoted from a letter from Stuart Harrington of the Mayo Clinic, dated July 18, 1922, in which it was stated that twenty-five cases of solitary cyst of the liver had been observed and operation performed at the Mayo Clinic. In 1926, Harrington3reported the successful removal of a multilocular hemorrhagic cyst of the liver. Orr and Thurston4added another case in 1927, and collected thirteen other instances
