title: Giant bilateral renal angiomyolipomas: a case report.
abstract: Angiomyolipoma (AML) is a mesenchymal renal tumor composed of variable proportions of adipose tissue as well as vascular and smooth muscle elements. It can cause important, potentially life-threatening complications. The aim of this case report is to show a conservative treatment modality of this disease. A 50-year-old man underwent ultrasonography and then computed tomography showing the presence of bilateral renal masses of 27.5 × 19.5 × 21 cm on the left kidney and 28.5 × 19.6 × 27.5 cm on the right, respectively. Serum creatinine was normal; an ultrasonography-guided biopsy of the left kidney did not allow a diagnosis with absolute certainty, but was suggestive of AML. The patient also underwent total body magnetic resonance imaging, which was negative for pathological findings. He underwent a strict regime of surveillance with magnetic resonance imaging every 4-5 months, and at the last follow-up he was asymptomatic and serum creatinine was still normal. The management of giant AML is a complex and multifactorial decision. Patients can knowingly choose an active surveillance program, even in case of giant AMLs.
