Tuberous sclerosis-associated renal angiomyolipoma: A report of two cases and review of the literature.

Abstract

In the general population, tuberous sclerosis-associated renal angiomyolipoma (RAML) is a rare benign hamartoma with potentially life-threatening complications and a poor prognosis. The two patients reported in the present study, who were diagnosed with bilateral RAML and spontaneous rupture of the RAML with tuberous sclerosis, presented with flank pain, abdominal pain, hemorrhage, hematuria and multiple lesions. The two cases are representative examples of the disease, and highlight the importance of determining the risk of acute hemorrhage in the early stages, and the significance of timely and proper treatment.
