Percutaneous aspiration and absolute ethanol sclerotherapy in the treatment of symptomatic bronchogenic cyst.

ABSTRACT

Surgical treatment is indicated for both symptomatic and asymptomatic bronchogenic cysts. The goal of treatment is total removal of the cyst. Percutaneous aspiration and absolute ethanol sclerotherapy is an effective, minimally invasive, and safe alternative method. We present the case of a 74-year-old woman with a symptom of persistent dry cough for 5 months. Plain and contrast-enhanced chest computed tomography revealed a large superior mediastinal cyst that could be easily accessed percutaneously. The cyst was treated by aspiration and ethanol sclerotherapy under ultrasound guidance and fluoroscopy. The patient was discharged a day later without complications. Chest CT at 6 months follow-up showed complete regression of the cyst.
