Endometriosis is an uncommon condition, and its occurrence in the urachus is exceptionally rare. This case report highlights the extreme rarity of bladder endometriosis involving the urachal area. To the best of our knowledge, no such cases have been previously reported in the literature. The clinical presentation and imaging findings of this condition are extremely similar to those of urachal carcinoma, which makes the differential diagnosis particularly challenging. In this case, a 34-year-old woman presented with significant bladder irritative symptoms during menstruation. Imaging revealed a mass in the urachal region, but its characteristics remained uncertain. Cystoscopy showed only bladder compression, and the patient ultimately underwent robot-assisted laparoscopic partial cystectomy. Postoperative pathology confirmed the diagnosis of bladder endometriosis. This case underscores the importance of considering bladder endometriosis in the differential diagnosis of masses in the urachal area, particularly when they resemble urachal cancer. Early surgical intervention and histopathological confirmation are essential to prevent disease progression.
子宫内膜异位症是一种不常见的病症，其在脐尿管中的发生极为罕见。本病例报告强调了累及脐尿管区域的膀胱子宫内膜异位症极其罕见。据我们所知，此前文献中未曾报道过此类病例。该病症的临床表现和影像学表现与脐尿管癌极为相似，这使得鉴别诊断极具挑战性。在本病例中，一名34岁女性在月经期间出现明显的膀胱刺激症状。影像学检查显示脐尿管区域有一个肿块，但其特征仍不明确。膀胱镜检查仅显示膀胱受压，患者最终接受了机器人辅助腹腔镜部分膀胱切除术。术后病理证实为膀胱子宫内膜异位症。本病例强调了在脐尿管区域肿块的鉴别诊断中考虑膀胱子宫内膜异位症的重要性，尤其是当它们类似脐尿管癌时。早期手术干预和组织病理学确诊对于防止疾病进展至关重要。
