Preoperative diagnosis of angiomyolipoma of the liver.

We experienced a case of surgically proven hepatic angiomyolipoma, a rare primary benign lipomatous tumor, which was preoperatively diagnosed by defining of its characteristic histologic components and benign radiologic nature with various imaging modalities. It was the first case that full radiologic evaluation was taken and internal vascular proliferation was defined by using dynamic bolus computed tomography (CT) prior to angiography.
