Bilateral Renal Angiomyolipoma: Involvement of the Contralateral Kidney after 25 Years – An Unusual Case

Abstract

The diagnosis of renal angiomyolipoma often poses problems, both clinically and pathohistologically. With the increasing refinement of imaging techniques it is becoming potentially possible to recognize these benign neoplasms by means of ultrasound, computed tomography and magnetic resonance imaging. Electron microscopy and histochemical methods are often necessary for the correct pathological diagnosis. The problems involved are presented on the basis of the case history of a patient who suffered from renal angiomyolipoma in both kidneys with an interval of 25 years. The first tumor was diagnosed histologically as a liposarcoma 25 years ago.

Laparoscopic donor nephrectomy in a patient with previous upper pole partial nephrectomy

“…A single case report presents the development of a contralateral AML 25 years after nephrectomy. 3 In vivo excision has been reported as well. Chen et al 4 performed an open partial nephrectomy, under cold ischemia, before removal of the organ for transplantation.…”

Value of Routine Sonography in the Diagnosis and Conservative Management of Renal Angiomyolipoma

“…among men [6,7], predominantly occurring between the ages 40 and 60. They frequently present as asymptomatic minor lesions, and 20-50% of cases are associated with tuberous sclerosis (Bourneville's disease), which in turn has been shown to be linked with angiomyolipomas in 40-80% of cases [8].…”
