A 31-year-old male with dysphagia and chest pain presented to our hospital. CT demonstrated a 6.3 × 3.7 cm low-density mass at the distal esophagus without enhancement. Endoscopic ultrasound (EUS) confirmed a 5.0 × 4.0 cm hypoechoic cystic-solid mass covered by smooth mucosal, part of the mass was associated with the esophageal muscle layer. Color Doppler ultrasonography and ultrasound elastography demonstrated the mass lacked blood flow and softness (Fig. 1). A minimally invasive treatment was appropriate after discussing. EUS served to guide the incision site, after the muscle layer was cut by a dual knife, copious brown mucinous fluid was drained from the cyst. A biopsy was taken from the cyst wall for histopathologic examination. The cavity was sprayed with saline solution and lauromacrogol in turn until the cyst wall turned white, then a few amounts of lauromacrogol remain to ablate the cyst. Clips were used to close the incision. Histopathology revealed a respiratory ciliated columnar epithelium-lined cyst wall, indicating the diagnosis of a bronchogenic cyst. During 9 months of follow-up, the patient was asymptomatic, endoscopy revealed the cyst was almost undetectable and CT suggested a considerable decrease in lesion size (Fig. 2).
