A urachal mass is a relatively rare presentation to the urologists' practice, often requiring radical surgical excision for a definitive diagnosis. Xanthogranulomatous inflammation of the urachus is an extremely rare entity with few cases reported worldwide, and to the best of our knowledge, no cases reported in the western world.
In this case, a 55-year-old male patient presented with bothersome lower urinary tract symptoms and computed tomography findings demonstrating a urachal mass that was worrisome for urachal carcinoma. Following surgical intervention, histopathology revealed urachal xanthogranuloma. Post-operatively, the patient recovered well, and eventually, he had symptomatic and radiologic improvement.
This case brings awareness to a rare presentation of a urachal mass-urachal xanthogranuloma. While operative intervention was both diagnostic and therapeutic, we highlight the challenge in differentiating between benign and malignant processes for urachal masses. Herein, we show the importance of including urachal xanthogranuloma in the differential diagnosis of a urachal mass to prevent further morbidity associated with the treatment of this disease.
脐尿管肿块在泌尿科医生的临床实践中相对少见，通常需要彻底的手术切除以明确诊断。脐尿管黄肉芽肿性炎症是一种极其罕见的疾病，全球范围内报道的病例很少，据我们所知，在西方世界尚无报道。
本例为 55 岁男性患者，因下尿路症状困扰就诊，计算机断层扫描（CT）发现脐尿管肿块，提示脐尿管癌。经手术干预后，组织病理学检查显示为脐尿管黄肉芽肿。术后患者恢复良好，最终症状和影像学均有改善。
本例提示了一种罕见的脐尿管肿块表现——脐尿管黄肉芽肿。虽然手术干预具有诊断和治疗双重作用，但我们强调了鉴别脐尿管肿块良恶性过程的挑战。本文强调了在鉴别诊断脐尿管肿块时将脐尿管黄肉芽肿纳入其中的重要性，以避免因治疗这种疾病而导致的进一步发病。
