Bacillus Calmette-Gu érin–induced kidney granulomas

A 59-year-old woman presented with asymptomatic right kidney masses on surveillance computed tomography. She underwent transurethral resection of the bladder tumor for urothelial carcinoma 3 months prior and received regular intravesical Bacillus Calmette-Gu érin therapy. Abdominal computed tomography showed multiple mild homogeneous enhancement masses in the right kidney (Figure 1a). Magnetic resonance imaging demonstrated masses with hyperintensity on the diffusion-weighted image (Figure 1b). Coronal contrast–enhanced magnetic resonance revealed masses with hypointensity located at the superior pole of the right kidney (Supplementary Figure S1).
