Clinical features and management of bronchogenic cysts: Report of 17 cases

Abstract

Between 1966 and 1996, 17 patients, comprising 1 child and 16 adults, underwent surgical treatment for bronchogenic cysts at the National Cancer Center Hospital. The bronchogenic cysts were located in the mediastinum in 11 patients and in the pulmonary parenchyma in 6. Of the 17 patients, 5 (29.4%) manifested symptoms, being more frequently seen in those with intrapulmonary cysts than in those with mediastinal cysts. Chest radiographs were ineffective for accurate preoperative diagnosis, but accurate diagnosis was possible with 69.2% of computed tomography (CT) scans and 100% of magnetic resonance imaging (MRI) scans. MRI also proved very useful for qualitatively diagnosing the mediastinal tumors as cystic or solid. Surgery was performed through a thoracotomy in 14 patients and by video-assisted thoracic surgery (VATS) in 3 patients, achieving complete resection in 16 patients. In one patient, a mediastinal bronchogenic cyst was excised by VATS and incompletely resected because of tight adhesion to the membranous part of the trachea; however, no late complication or recurrence developed after the residual cystic wall had been ablated by electrocautery. VATS, which is an easy procedure to perform with only minimal surgical invasion, may be indicated for bronchogenic cysts if patients who undergo incomplete resection can be followed up carefully. Recent advances in imaging techniques have made it unnecessary to perform surgical excision for diagnostic confirmation, but we recommend surgery for most patients to relieve symptoms and prevent complications.

Lipoma-Like Bronchogenic Cyst in the Right Chest Sidewall: A Case Report and Literature Review

“…According to the literature, the preoperative CT diagnostic accuracy rate was 69.2%, while MRI diagnostic accuracy rate was 100%. 15) Therefore, McAdams et al suggested that CT is useful for initial evaluation of bronchogenic cysts, while MRI is needed for differentiation of high attenuation cysts from soft tissue masses. 4) In the past, we only knew that bronchogenic cysts occur most commonly in the lungs and mediastinum, but never experienced the cases with the cyst located outside of the parietal pleura in the chest cavity.…”

Bronchogenic cysts in adults: frequently mistaken for a solid mass on computed tomography

“…However, to confi rm the cystic nature of a lesion based on HU, we considered lesions with values below 20 HU as cysts. In other cases magnetic resonance imaging can be used to identify bronchogenic cysts, and discriminate between solid and cystic masses, especially in cases with a high number of HU, giving an intense signal on T2-weighted MRI [12][13][14]. Alternatively, an EUS can usually distinguish between cystic and solid lesions, depending on location of the cyst in relation to the esophagus [9,15].…”

Refractory Wheeze: A Rare Presentation of Mediastinal Type Bronchogenic Cyst In A Child

“…[9] A symptomatic bronchogenic cyst is an indication for surgical removal by either cyst excision or lobectomy by open thoracotomy or video assisted thoracic surgery (VATS). [10] There are controversies regarding whether an incidentally found bronchogenic cyst warrants operation or not, but as the course of these pathologies are unpredictable, several surgeons prefer preventive surgery.
