Renal parencymal malacoplakia successfully treated with conservative therapy; a case report

Malacoplakia is a relatively rare form of chronic granulomatous inflammation. Which occurs most frequently in the genito-urinary system, but renal parenchymal involvement is rare. We present a case of malacoplakia of the renal parenchyma. A 69-year-old woman with left renal mass was referred to our department. Abdominal enhanced CT scan revealed heterogeneous mass in the left kidney (50 x 45 mm). CT-guided percutaneous left renal needle biopsy confirmed the diagnosis of renal malakoplakia. We successfully treated her with oral levofloxacin. The lesion resolved after the 4-months-therapy, and there has been no recurrence for 22 months since the treatment.
