Abstract

Mediastinal cysts are rare benign lesions and their diagnosis and treatment remain difficult and controversial. The development of endoscopic ultrasound (EUS) has broadened the horizon for the precise treatment of diseases. The present study reports the case of a 53‑year‑old male hospitalized with chest pain. All imaging findings, including computed tomography, magnetic resonance imaging and EUS, indicated a benign cystic mass in the posterior mediastinum. The posterior mediastinal cyst was treated with EUS‑guided fine‑needle aspiration combined with an intracapsular injection of antibiotics and ethanol, and the results indicated no mediastinal infection after the puncture and no recurrence after 3 months of follow‑up. The present study provides a new method for diagnosing and treating mediastinal cysts.
