Bilaterale renale Angiomyolipome mit Thrombus in der Vena cava inferior

Abstract

Renal angiomyolipomas are mesenchymal tumors that are composed of fat tissue, smooth muscle cells and vessels. These are benign tumors, but in rare cases they show a more aggressive growth pattern with invasion into the venous system but without revealing any signs of malignancy. We report a new case of bilateral renal angiomyolipomas with a caval thrombus in a 36 year old female patient with tuberous sclerosis, and give a brief review of the related literature.
