The solitary rectal ulcer syndrome is a distinct clinical entity occurring mainly in young patients who experience rectal bleeding. Solitary, and occasionally multiple, ulcers occur predominantly on the anterior or anterolateral aspects of the rectum. Current theories attribute this to pelvic muscle discoordination during defecation with partial rectal mucosal prolapse and traumatic ulceration. Classical histologic changes have been demonstrated that enable accurate diagnosis by the pathologist. Ten cases of biopsy-proven solitary rectal ulcer syndrome were reviewed. The radiographic abnormalities were: nodularity of the rectal mucosa (three cases), stricture formation (two cases), polypoid rectal masses (two cases), and ulceration (two cases). Radiologically this condition must be differentiated from other more serious entities such as carcinoma or inflammatory bowel disease.
孤立性直肠溃疡综合征是一种独特的临床病症，主要发生在有直肠出血症状的年轻患者身上。溃疡多为单发，偶尔也有多发，主要出现在直肠的前侧或前外侧。目前的理论认为，这是由于排便时盆腔肌肉失调，导致部分直肠黏膜脱垂并形成创伤性溃疡。已证实的典型组织学变化有助于病理学家进行准确诊断。回顾了10例经活检证实的孤立性直肠溃疡综合征病例。影像学异常表现为：直肠黏膜结节状（3例）、狭窄形成（2例）、直肠息肉样肿物（2例）和溃疡形成（2例）。在影像学上，这种病症必须与其他更严重的疾病如癌症或炎症性肠病相鉴别。
