Résumé

BACKGROUND: Renal angiomyolipomas (AMLs) are frequent in tuberous sclerosis and are responsible for a significant proportion of the morbidity in adulthood, mainly from bleeding complications, which are correlated to the size of the AMLs. We describe the case of a 19-year-old female with multiple bilateral renal angiomyolipomas. CASE PRESENTATION: The renal AMLs measured up to 6 cm in size. She was first treated with a low dose of the mammalian target of rapamycin (mTOR) inhibitor sirolimus (up to 3 mg/day over a 12-month period) and following significant AML size reduction, percutaneous cryoablation was performed. No side-effects of either treatment were reported. At 12 months post-cryoablation, no recurrence of the AML was noted. CONCLUSION: This is the first report of this treatment strategy and the case study reveals that combining a low dose of an mTOR inhibitor with percutaneous cryoablation to treat small tumors mitigates the side-effects while providing a good clinical outcome. This therapeutic approach is a novel tool for the clinician involved in the management of patients with tuberous sclerosis.
