【摘要】Objective To analyze the imaging features of hepatic angiomyolipoma (HAML) on computed tomography (CT) and magnetic resonance imaging (MRI).Methods The imaging fingdings of 18 tumors which were pathologically diagnosed as HAML after surgery were analyzed retrospectively.Before operation,twelve and ten patients underwent CT and MRI non-contrast and dynamic enhanced scans,respectively,and 4 patients received both examinations.The imaging
characteristics
including
the
number,diameter,location,appearance of the lesions,plain and dynamic enhancement mode were analyzed.Results Eighteen HAML lesions were found in 18 patients with a diameter ranging from 1.5 cm to 17.2 cm (mean 5.3 cm).Five lesions manifested fatty content,and one showed hemorrhage and necrosis.Five HAMLs enhanced in a \and fast-out\mode,eleven in a \and slow-out\mode and two other lesions in an irregularly discrete mode.The arterial supply was found in 11 HAMLs in the hepatic arterial phase,all coming from intrahepatic arteries.Intratumoral vessels were observed in 12 HAMLs.Early draining veins to the hepatic vein (n =3) and portal vein (n =1) were detected in
