title: Xanthogranulomatous inflammation of urachus mimicking urachal carcinoma.
abstract: Urachal xanthogranuloma is rare. In this case, the patient presented with a lower abdominal mass and elevated inflammatory markers. The computed tomography findings of xanthogranulomatous urachitis resemble those of urachal carcinoma and, although rare, this entity should be included in the differential diagnosis of urachal masses.
