[Ethanol Instillation for Mediastinal Cyst].

Area of Science:

• Thoracic Surgery
• Interventional Radiology
• Medical Imaging

Background:

• Mediastinal cysts are uncommon and typically asymptomatic.
• Symptomatic presentation often results from compression of adjacent thoracic organs.
• Treatment options include surgical resection or percutaneous decompression.

Observation:

• A 53-year-old female patient presented with dyspnea and conversational difficulty.
• Imaging revealed a large mediastinal cyst occupying the right chest cavity.
• The patient had a history of intractable epilepsy, mental retardation, and Chilaiditi syndrome.

Findings:

• Percutaneous aspiration and ethanol instillation were successfully performed.
• This minimally invasive approach effectively treated the symptomatic mediastinal cyst.

Implications:

• Percutaneous ethanol instillation is a viable and effective treatment for symptomatic mediastinal cysts.
• This method provides an alternative when surgical intervention is contraindicated or high-risk.
