Cystic primary neoplasms of the liver of the adult. CT features.

Although rather rare, primary cystic neoplasms of the liver of the adult may represent a diagnostic challenge in everyday practice. We describe the features of such tumors visualized on computed tomography. This shows a wide range of morphological changes such as septa, papillary growths, solid/liquid ratio, wall characteristics, and vascularization. We conclude that although the differential diagnosis between these tumors and nontumoral cystic lesions may occasionally be reliable on computed tomography, proper management of hepatic cystic neoplasms still relies on the pathological findings.
