Renal malakoplakia is a rare inflammatory disorder that predominantly affects the bladder, but has also been known to affect the kidneys. We present a case of a young woman with renal malakoplakia and concomitant E. coli bacteremia. The patient underwent numerous imaging studies during her clinical evaluation including ultrasound, magnetic resonance imaging, and computed tomography with 3-dimensional and cinematic renderings. Diagnosis was ultimately confirmed with renal biopsy which demonstrated Michaelis-Gutman bodies, a pathognomonic pathological finding in malakoplakia. She was started on antibiotics as well as bethanechol and ascorbic acid. Although her renal function improved with this treatment, she continued to have signs and symptoms of infection and she is planned for upcoming left nephrectomy.
