Benign tumors of the esophagus can be classified as mucosal or submucosal in origin. The most common mucosal lesions include squamous papillomas, adenomas arising in Barrett's mucosa, inflammatory esophagogastric polyps, and glycogenic acanthosis. These benign mucosal lesions can often be diagnosed on double-contrast esophagrams based on their characteristic radiographic findings. Major submucosal or intramural lesions include leiomyomas, leiomyomatosis, fibrovascular polyps, granular cell tumors, and duplication cysts. Despite their infrequency, these lesions also can often be diagnosed on esophagography and/or CT based on their characteristic radiographic findings. The purpose of this article is to review in some detail the radiographic features of these various benign tumors of the esophagus.
食管良性肿瘤可根据起源分为黏膜性或黏膜下性。最常见的黏膜病变包括鳞状乳头状瘤、Barrett黏膜中发生的腺瘤、炎性食管胃息肉和糖原棘皮症。这些良性黏膜病变通常可根据其特征性的放射学表现，在双重对比食管造影上得以诊断。主要的黏膜下或壁内病变包括平滑肌瘤、平滑肌瘤病、纤维血管息肉、颗粒细胞瘤和重复囊肿。尽管这些病变并不常见，但根据其特征性的放射学表现，通常也可在食管造影和/或CT上作出诊断。本文旨在较为详细地综述这些食管良性肿瘤的放射学特征。
