Colitis cystica profunda (CCP) mimicks rectal carcinoma, which makes distinguishing this benign lesion from the more common rectal neoplasm clinically and pathologically difficult. When transrectal ultrasound (US) was used in this case, three features of CCP were seen. There were multiple lesions, which did not penetrate beyond the submucosa. A large cystic component was seen, with a layer of uniform thickness in two of the three lesions. Non-solid contents and a lack of infiltration can be visualized at transrectal US, which helps diagnose CCP.
深部囊性结肠炎（CCP）酷似直肠癌，这使得在临床和病理上区分这种良性病变与更常见的直肠肿瘤很困难。在该病例中使用经直肠超声（US）时，发现了CCP的三个特征。有多个病变，未穿透黏膜下层。可见一个大的囊性成分，在三个病变中的两个中具有均匀厚度的一层。经直肠超声可显示非实性内容物且无浸润，这有助于诊断CCP。
