Case report: variable imaging appearances of angiomyolipomas of the liver.
Angiomyolipomas of the liver are rare benign tumours. We describe the variable imaging appearances of these tumours in three women. The first two patients underwent ultrasound, computed tomography (CT) and angiography, which demonstrated lesions resembling focal nodular hyperplasia and hepatocellular carcinoma, respectively. Both had histologically-proven liver angiomyolipomas surgically resected. The third patient was incidentally found to have typical features of multicomponented liver angiomyolipoma on CT. Variable proportions of fatty tissue in these tumours are the most likely explanation for their different imaging appearances on CT.
