Renal Angiomyolipoma: Beyond Size Criteria for Predicting Rupture
Author(s): Simon McQueen*, Alexander Coombes and David Benz
Background: Renal Angiomyolipoma (AML) are vascular tumors that while histologically benign, carry a risk of potentially life threatening haemorrhage. Selective Arterial Embolization (SAE) has been demonstrated as effective treatment, however given most tumours are asymptomatic the challenge facing clinicians is in selection of which AML should undergo treatment. Historically size criteria have been used, but other factors such as tumour vascularity may help guide treatment choices.
Methods: Retrospective cohort analysis of all SAE treated AML at our quaternary level institution in the last ten years, evaluating tumour size, presence of intratumoral aneurysm and aneurysm size as a predictor of spontaneous haemorrhage.
Results: Twenty-seven renal AML underwent SAE. Five tumours had presented with spontaneous haemorr.. View More»
