case_images: (A,B) CT scan revealed a mass of soft tissue density in the urachal area at the anterior upper edge of the bladder, approximately 32 mm x 33 mm x 29 mm in size, with unclear boundary with the bladder (arrow). (C,D) VCUG findings: No filling defects or diverticula were observed during bladder filling and emptying, and there was no reflux in the bilateral ureters.

case_images: The boundary between the lower margin and the bladder was unclear, prompting consideration of infectious or space-occupying lesions (Figures 1A,B). VCUG revealed no abnormality in bladder shape or size, no filling defect or niche in the bladder, and no bilateral ureteral reflux (Figures 1C,D).
case_images: (A) Intraoperative cystoscopy revealed a round lesion near the bladder neck, measuring approximately 8 mm x 6 mm, with a central fistula (arrow). (B) A mass was observed at the top of the bladder during laparoscopy, measuring approximately 28 mm x 25 mm (arrow). (C) Cystoscope-assisted laparoscopic provides surgical area positioning for surgery (arrow). (D) Postoperative pathology showed that the lesions in the bladder and those outside the bladder were consistent with a urachal cyst with acute and chronic suppurative inflammatory changes.

case_images: During the operation, cystoscopy revealed a circular mass near the top of the bladder neck, measuring 0.8 cm*0.6 cm, with a fistula in the middle and a small amount of blood clot attached to the surface (Figure 2A). Subsequently, laparoscopy revealed a hard mass at the top of the bladder (Figure 2B), measuring about 28 mm x 25 mm. As a result, foreign body forceps were used to clamp the tumor and gently push it outward to facilitate localization of the operative area for laparoscopy (Figure 2C). Postoperative pathology showed that the lesions in the bladder and those outside the bladder were consistent with a urachal cyst with acute and chronic suppurative inflammatory changes (Figure 2D).
