Esophageal fibrovascular polyps are benign intraluminal submucosal pedunculated tumors that can grow significantly and cause dysphagia symptoms. They usually occur in the upper third of the esophagus, at the level of the upper esophageal sphincter.
They were previously denominated as lipomas, fibromas, or fibrolipomatous polyps of the esophagus, but all these terms have been replaced accordingly to the World Health Organization classification system 1-3.
Symptoms are related to the size of a tumor with dysphagia being the most common complaint. Respiratory symptoms are also frequent and cases of tumors with long stalk being regurgitated into the pharynx have been described as a cause of death from asphyxiation 4-5.
Can occasionally be identified as a right-sided superior mediastinal mass with associated anterior tracheal bowing.
Proximal esophagus intraluminal filling defect mass with smooth contours extending inferiorly into the thoracic esophagus.
Well-defined solid mass expanding the lumen of the proximal esophagus. Fat-attenuated components may be present in lesions with abundant adipose tissue 1.
