ABSTRACT

Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis, which frequently has a pseudotumoral appearance, as a result of which differential diagnosis with malignant renal neoplasia is difficult, especially as there are no specific signs of this lesion. The aim of this article is to notice the various histological, clinical and radiological characteristics, and the different modalities of diagnostic and treatment of this affection.
