摘要
Introduction: Rupture of renal angiomyolipoma (AML) is an emergency and life-threatening complication. This study aimed to evaluate the association of computed tomography (CT) scan parameters with the risk of rupture in renal AMLs.
Methods: In this retrospective cross-sectional study, patients who were referred to a referral university hospital with diagnosis of AML, between 2007 and 2019, were included. Patients were divided into ruptured and non-ruptured cases based on surgery and CT scan findings and the baseline characteristics as well as CT scan parameters were compared between the two groups.
Results: 20 AML patients with the mean age of 39.6 ± 12.5 years were included (75% female). The lesion was ruptured in 8 (40%) patients. The mean size of the lesion was 97.0 ± 15.9 mm in the ruptured and 72.0 ± 29.4 in the non-ruptured AML (p = 0.045). The mean fat density based on non-contrast enhanced CT (NCCT) scan (-56.1 ± 16.3 vs -74.9±24.1; p = 0.018) and contrast enhanced CT (CECT) scan (-20.8 ± 16.9 vs -50.5 ± 31.7; p = 0.016) was significantly higher in the ruptured cases. Total tumor density based on NCCT scan was significantly greater in the ruptured AMLs (19.6 ± 25.9 vs -22.7±41.6, p=0.033).
Conclusion: It seems that some CT scan parameters such as mean fat density and total tumor density could be used for differentiation between ruptured and non-ruptured AMLs.
