Abstract:
Except for squamous cell carcinoma and adenocarcinoma, lesions that protrude into the esophagus are rare, and include benign and malignant tumors. The imaging findings of these lesions on esophagography, computed tomography (CT), and magnetic resonance imaging (MRI) are often non-specific. However, some of them reveal characteristic imaging findings. In addition, esophagography, CT, and MRI are useful to evaluate location, extent, invasion, vascularity, lymphadenopathy, and metastasis. Knowledge of the imaging features of protruding esophageal lesions helps to narrow the differential diagnosis. We describe the main features of esophageal protruding lesions.
