What is an esophageal cyst?

Esophageal cyst is a rare benign esophageal disease, usually one or more cystic masses under the esophageal mucosa, varying in size.

Esophageal cysts can be congenital or acquired, most occur in the middle or lower esophagus, and can extend to the neck or mediastinum. Common symptoms of esophageal cysts include difficulty swallowing, chest pain, cough, shortness of breath, and difficulty breathing. When the cyst ruptures or becomes infected, symptoms such as hematemesis, bloody sputum, and bloody stool may occur.

Medical treatment is recommended for small, asymptomatic esophageal cysts, and surgery is recommended for large, symptomatic esophageal cysts, or patients suspected of malignancy.
