Asymptomatic bronchogenic cysts: what is the best management?
The management of patients with uncomplicated bronchogenic cysts has evolved over the last decade with the development of more precise diagnostic techniques and a better understanding of the variable natural history of these lesions. Although an aggressive surgical approach is still indicated for infants and children, it is acceptable to treat asymptomatic bronchogenic cysts in adults in a conservative manner. Observation alone may be indicated for small, classic, asymptomatic cysts. The use of mediastinoscopy or percutaneous or transbronchial needle techniques for carinal or paratracheal cysts offers the option of fluid aspiration or wall biopsy, thus avoiding thoracotomy. An air-fluid level in the cyst, the presence of malignant cells in the aspirate or biopsy, the development of symptoms, or enlargement or recurrence of the cyst on follow-up examination mandates complete surgical removal at thoracotomy. This is also indicated for intraparenchymal bronchogenic cysts, which are more prone to bronchial communication and infectious complications and for which the distinction from a carcinoma with a cystic component may be difficult.
