Abstract: Objective The aim of this study was to investigate the imaging feature of patients with microvesicular polycystic liver diseases (PLD). Methods A total of 60 patients with PLD were enrolled in this study, and all patients were undergone computer tomography (CT), magnetic resonance imaging (MRI) and ultrasonography (US) examination. Results Out of the 60 patients selected, 19 had hepatomegaly, 25 had obvious gastrointestinal symptoms, and 6 had abdominal mass, while most patients had normal serum liver function tests; the main CT findings in this 60 patients with PLD were as follows: a circular low-density images of different sizes scattered in the liver parenchyma, numerous numbers, no enhancement, and accompanied or not accompanied with liver enlargement; the MRI showed scattered long T1 and long T2 signals in the liver parenchyma, with different sizes of numerous numbers, without enhancement, and some patients had liver enlargement; the ultrasonography showed that the echoes of liver parenchyma increased unevenly, showing patchy, stripy and multiple hypoechoic areas in different sizes, and some of them were especially small in diameter. Conclusion Although CT and MRI have obvious advantages in the diagnosis of patients with PLD, the ultrasonography might easily demonstrate the manifestations and features of patients with microvesicular polysystic liver disease.
