Abstract: Objective: To study the imaging features of CT, MR, and pathologic findings of hepatic angiomyolipoma (HAML), and to increase knowledge about this disease. Methods: The imaging findings of ten patients with HAML confirmed pathologically were analyzed and were controled with histopathologic findings. Results: Nonenhanced CT demonstrated heterogeneously hypoattenuating masses with a well-defined margin, in which some spots and tiny linear prominent hypoattenuated area were observed. On MRI, the masses were mainly hypointense in three cases, with some hyperintense portions within it on T1WI, and heterogeneously hyperintense masses were revealed on T2WI. One case showed "target"sign, the tumor was hyperintense with a central hypointense area on T1WI that was similar to the appearance of prominent hypoattenuated mass with a central isoattenuatied area on plain CT. As on enhanced CT, showed the tumors as markedly enhanced on arterial phase, moderately and slightly enhanced on portal venous and (or) delayed phase. Pseudoaneurysm was found within the tumor in one case, and pseudocapsule detected in two cases showed rim enhancement on portal venous and (or) delayed phase. Conclusion: The imaging features of CT, MR can represent the basic component of the tumor, the tiny fat component detected on images and enhanced characteristics of the tumors may be helpful for the correct diagnosis of HAML.
