Contrast-enhanced computed tomography (CT) of the abdomen was suggestive of a smooth-walled, cystic mass measuring 5 x 5 x 6 cm, located above the bladder (Fig. 1).
(A) At exploration, the mass was superior to the urinary bladder. (B) White pultaceous material was seen on incising the mass. (C) The mass was separated from the urinary bladder.

With gentle blunt and sharp dissection, the mass was separated from the bladder and could be excised en bloc (Fig. 2).
(A) Photomicrograph showing the urothelial lining (arrow) and a granuloma (dashed arrow) (H&E, x 10). (B) Multiple epitheloid cells, lymphocytes, caseation, and an occasional Langhans giant cell, suggesting tuberculosis (H&E, x 10).
