Revisiting angiomyolipomas: The significance of a rich blood supply on imaging for risk-adapted decision making.

ABSTRACT:

Purpose

Active surveillance is the preferred management for most renal angiomyolipomas (AMLs) but no risk-adapted follow-up strategy has been established. We aimed to assess the dynamics associated with hemorrhagic complications (HC) and tumor growth (TG) at long-term follow-up of AMLs.

Materials and methods

A single-center retrospective study was conducted, enrolling patients with an AML diagnosed by computed tomography or magnetic resonance imaging. Kaplan-Meier analyses were performed to estimate HC risk and multivariate logistic regression analyses were carried out to evaluate predictors of TG and HC.

Results

A total of 150 patients were included. The median follow-up was 64.5 months (interquartile range [IQR] 25-102). Median tumor size at diagnosis was 14 mm (IQR
