Tailgut cysts are derivatives of the embryonic post-anal gut. Usually asymptomatic, they are discovered in adult life as an incidental retrorectal mass. Complications include infection, with the formation of retrorectal abscesses and occasionally and fistulae, and a long-term risk of malignant change, which means that once discovered surgical excision is advised. We present a case that was assessed pre-operatively with transrectal ultrasound. The findings were of a well defined cystic lesion, with no evidence of invasion. We believe that transrectal ultrasound is of value in assessing retrorectal lesions.
尾肠囊肿是胚胎肛门后肠的衍生物。通常无症状，在成年期作为偶然发现的直肠后肿物被发现。并发症包括感染，可形成直肠后脓肿，偶尔形成瘘管，以及长期的恶变风险，这意味着一旦发现建议手术切除。我们报告一例术前经直肠超声评估的病例。检查结果为边界清晰的囊性病变，无浸润迹象。我们认为经直肠超声在评估直肠后病变方面具有价值。
