title: Renal malacoplakia: demonstration by MR imaging.
abstract: We report herein a case of histologically verified bilateral renal malacoplakia. MRI features were distinctive and include multiple nodules 1-2 cm in diameter that were low in signal on T1, T2 and early and late post gadolinium images with intervening fibrous stroma. Demonstration of renal malacoplakia on MR images may obviate the need for major surgery and rapidly direct patients to appropriate antimicrobial therapy for treatment.
