Differentiation of esophageal duplication cysts from esophageal bronchogenic cysts: A case report and literature review

Esophageal bronchogenic cysts located in inferior esophagus are rare. Here, we report on the case of a 12-year-old female patient who presented at our institution with dyspepsia and abdominal distention for 2 years with no other symptoms. Physical examination of abdomen and chest was negative, and laboratory tests did not show any abnormal results. However, computed tomography imaging showed a mass of about 8 cm × 8 cm × 4 cm in the lower esophagus compressing the stomach. The preoperative diagnosis was determined to be an inferior esophageal duplication cyst. A transabdominal excision of the cyst was performed 5 days after hospital admission. Pathology revealed an esophageal bronchogenic cyst. The case report and literature shows that differences exist between esophageal duplication cysts and esophageal bronchogenic cysts.
