CT evidence of renal angiomyolipoma with subcapsular hemorrhage

Renal angiomyolipoma (AML) composed of adipose tissue, smooth muscle, and vessels can be clearly visualized on computed tomography (CT). However, once hemorrhage occurs, it is difficult to distinguish this lesion from other solid tumors. While there are reviews of AML with hemorrhage, those with the subcapsular type are rare. We present a case of preoperatively diagnosed angiomyolipoma complicated with subcapsular hemorrhage, as evaluated on CT. (author)
