Abstract：
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.
摘要：
黄色肉芽肿性肾盂肾炎（XPG）是一种已知的临床实体；然而，这种炎症病理进一步进展到邻近器官，包括输尿管,膀胱和尿道,极为罕见。输尿管黄色肉芽肿性炎症是一种慢性炎症状态，在固有层中可见泡沫巨噬细胞，多核巨细胞和淋巴细胞形成肉芽肿性炎症。这是良性的。根据其在计算机断层扫描（CT）扫描图像上的外观，很容易被误认为是恶性肿块,患者可能会接受可能导致并发症的手术。在这里，我们介绍了一名老年男性，其已知患有慢性肾脏疾病的病例，患有不受控制的2型糖尿病，并伴有发烧和排尿困难。经过进一步的放射学调查，患者有潜在的败血症，被发现有一个累及右输尿管和下腔静脉的肿块。活检和组织病理学检查，他被诊断为黄色肉芽肿性输尿管炎（XGU）。患者接受了进一步治疗并进行了随访。
