%X Xanthogranulomatous pyelonephritis (XPG) is a known clinical entity; however, the further progression of this inflammatory pathology to adjacent organs, including the ureter, bladder and urethra, is extremely rare. Xanthogranulomatous inflammation of the ureter is a chronic inflammatory state where foamy macrophages are seen in the lamina propria along with multinucleated giant cells and lymphocytes forming a granulomatous inflammation, which is benign. Based on its appearance on computed tomography (CT) scan images, it can easily be misidentified as a malignant mass, and the patient can be subjected to surgery that can lead to complications. Here we present a case of an elderly male with a known case of chronic kidney disease with uncontrolled type 2 diabetes mellitus who presented with fever and dysuria. Upon further radiological investigations, the patient had underlying sepsis and was seen to have a mass involving the right ureter and inferior vena cava. Upon biopsy and histopathology, he was diagnosed with xanthogranulomatous ureteritis (XGU). The patient underwent further treatment and was followed up.
