Abstract

Mesenchymal origin of ureter tumors account for less than 3 percent of all primary ureteral tumors. Among mesenchymal tumors, primary leiomyoma of ureter is extremely rare. Here, we present a case of primary leiomyoma of ureter coexisting with renal cell carcinoma. When encountering well-defined homogeneously enhanced mass of ureter on computed tomography, radiologist should keep in mind that ureteral leiomyoma should be considered as differential diagnosis.
