[An exceptional case of renal angiomyolipoma extended to the inferior vena cava. Successfull surgical management].

The clinical case of a 39 years old female is reported, with the diagnosis of tumor of the right kidney extending into the infra-hepatic vena cava, assuming the shape of a floating thrombus. The patient underwent right radical nephrectomy, followed by resection of the intra caval tumor. Both the procedure and post operative course were uneventfull. Histopathological evaluation of the specimens, associated to specific imunohistochemistry studies, confirmed the diagnosis of angiomyolipoma of the kidney. A review of the literature concluded that this is the 27th case published of a kidney angiomyolipoma extending into the inferior vena cava, thus justifying its presentation and divulgation.
