Radiological Appearance of Renal Leiomyoma: two cases report and review of the literature

Renal leiomyomas are benign tumors originating from the smooth muscle cells of various renal structures, and are found in approximately 5% of the population based on autopsy series. However, their clinical incidence is much lower. Renal leiomyomas are usually small and discovered incidentally during imaging studies performed for various other reasons. Here we report 2 cases of incidentally found renal leiomyoma in 2 middle-aged women. The characteristic computed tomography findings are described and relevant literature is reviewed.
