[Non-parasitic solitary cysts of the liver (author's transl)].

Three cases of solitary benign livercysts are reported. The first one (250 cm3) was incidentally discovered during a cholecystectomy for lithiasis and was located in the vicinity of a hamartoma. The second one was enormous (4800 cm3), inflamed, adherent and displacing the nearby organs. The third one contained 3,600 cm3. The literature of this rather rare entity was reviewed and the symptomatology, clinical findings, laboratory results, liver scintigraphy, selective arteriography and especially the coaxial computer tomography scan which by itself just almost reveals the diagnosis, are discussed in function of our findings. The etiology of these tumors and their possible association with a hamartoma is discussed. A classification of kystic livertumors is proposed. The treatment of choice is a kystectomy and the prognosis is good.
