case_images: Magnetic resonance imaging (MRI) demonstrated a lobulated mass at the posterior aspect of the urinary bladder with 7.2 cm x 5.7 cm in diameter, which was presented as uterine leiomyoma (Figure 1). Furthermore, a small intramural mass was indicated at the aspect of the uterus with measures approximately 1 cm x 1 cm in diameter (Figure 1).
case_images: Grossly, the mass is white-red in color.

case_images: The reddish-white mass was noticed in the posterior aspect of the bladder wall thus partial cystectomy was performed (Figure 2).

case_images: The pathology of bladder mass revealed a benign mesenchymal neoplasm composed of interlacing bundles of smooth muscle fibers with a whirling pattern (Figure 3) which the diagnosis of bladder leiomyoma was confirmed (Figure 4).
case_images: Immunostaining for smooth muscle actin shows diffuse and strong cytoplasmic positivity in smooth muscle cells.
