title: [Spontaneous rupture of renal angiomyolipoma with tuberous sclerosis during long-term follow-up: a case report].
abstract: We present a case of spontaneous rupture of bilateral renal angiomyolipoma (AML) with tuberous sclerosis. A 46-year-old woman was admitted with sudden onset of severe left flank pain. She had been diagnosed to have bilateral AML with tuberous sclerosis 15 years earlier. Four years after the initial diagnosis, spontaneous rupture of right renal AML occurred and right renal embolization of the right renal artery was performed. The treatment for the left renal AML was not performed. Eleven years later in 2000, spontaneous rupture of contralateral renal AML occurred and left renal embolization of the left renal artery was performed. We evaluated the efficacy of selective arterial embolization in right AML and the change of the tumor size during a 10-year follow up after embolization. The right AML had decreased 86% in 11 years. Selective arterial embolization is an effective and safe treatment for AML. We evaluated the natural history of left AML and calculated the doubling time to be about 1,370 days for the first period of 4 years and about 2,075 days for the second period of 11 years. Although the growth change was very slow, we should observe the tumors carefully on computed tomography or ultrasound to prevent life-threatening hemorrhage.
