“…A carcinoid tumor of the rectum is usually slow growing compared with adenocarcinoma of the rectum because of its low-grade malignant nature, although it can be extensive or cause metastasis in its advanced stage [11]. Carcinoid tumors arise from Kulchitsky's cells located deep within the mucosal layer of the rectum [12].…”

Radiologic spectrum of rectal stenosis

et al. 2000

Rectal stenosis is a common condition caused by a wide variety of diseases, including both intrinsic and extrinsic disorders, as well as both malignant and benign pathologies. Barium enema, CT, and MRI are the primary modalities for the evaluation of the disease, and careful observation of the characteristic radiologic features usually leads to correct diagnosis. However, some of the lesions looks very similar and are difficult to differentiate from each other. The purpose of this study is to review the literature on diseases that cause rectal stenosis, to clarify the characteristics of radiologic features, and to suggest the limitations in differential diagnosis. Deliberate analysis of these imaging features and correlation with clinical manifestations can facilitate a more specific diagnosis.
