An Unusual Case of Aggressive Angiomyolipoma Invading the Left Renal Vein

Renal angiomyolipomas are the most common benign renal neoplasms containing smooth muscle, adipose tissue and blood vessels. In the vast majority of cases those lesions are an incidental finding and are asymptomatic. In small percent of cases the lesions may be symptomatic presenting with backpain, hematuria and spontaneous hemorrhage being the most common complication. On rare occasions angiomyolipomas can be found to be angioinvasive extending in to the renal vein, inferior vena cava or right atrium. In this case report we describe a case of a 34 years old woman presenting with angiomyolipoma of the left kidney with invasion of the renal vein.
