| Review Title: | Beyond adenocarcinoma: MRI of uncommon rectal neoplasms and mimickers |
| Abstract: | Objective: To provide a review of rare rectal tumors beyond adenocarcinoma. Results: Rectal cancer is a common malignancy, both in the United States and abroad. In addition to adenocarcinoma, abdominal radiologists will encounter a variety of other less common rectal masses, both benign and malignant neoplasms as well as non-neoplastic mimickers. Familiarity with these conditions and their characteristic features on MRI is useful in clinical practice. In this article, a number of such conditions are discussed, with an emphasis on distinguishing features on MRI of the rectum. Conclusion: Familiarity with the MRI features of rare rectal tumors beyond adenocarcinoma, as well as a small number of non-neoplastic mimics, is important for abdominal imagers to make diagnostic differentials and to assist in treatment planning. © 2019, Springer Science+Business Media, LLC, part of Springer Nature. |
