Evaluation of angiomyolipoma by ultrasound in correlation with computed tomography findings in Erbil province

Abstract

Background and objective: The benign renal mesenchymal tumor, angiomyolipoma (AML), consists of smooth muscle, fat and blood vessels, representing (1–3%) of the solid renal tumors. The most common type of benign renal tumors is accounting about (0.3–3%) of all kidney masses. AMLs are asymptomatic in general and found incidentally via routine imaging procedures and are seldom symptomatic. This study aimed to evaluate incidental findings of Angiomyolipoma by ultrasound in relation with CT findings in Erbil province. Methods: This descriptive cross-sectional study was conducted at the Rizgary Teaching hospital from March 2021 to April 2022. Review of ultrasound reports and CT scans data were collected from 61 patients with renal masses who attended to the public and private hospitals in Erbil province during the study period. The patients were older than 25 years in age. Results: The results showed that female of middle age were predominant among AML patients in the study. By using CT technique, 92.6% of females scored as hypoattenuating AML, and 88.5% of the AMLs were hyperdense or hyperattenuating by using CT technique. The results also revealed that 93.4% of AML cases were hyperechoic by Ultrasound technique, while 6.6% of the fat-poor were hyperechoic by using the Ultrasound technique. Conclusion: It can be concluded that female of middle age were predominant among AML patients, and CT technique is more accurate and sensitive in the diagnosis of AML cases.
