ABSTRACT
Xanthogranulomatous inflammation of the urachus is a very rare benign chronic inflammatory disease of an unknown etiology. Herein we report a case of a 31-year-old woman who complained of lower abdominal pain and dysuria. Cystoscopy revealed a bullous change at the dome of the urinary bladder. MRI revealed a cystic mass above the bladder dome that extended to the umbilicus. A partial cystectomy with urachal resection was performed. Pathological examination revealed xanthogranulomatous urachitis combined with bullous cystitis.
