Mediastinal bronchogenic cyst's recurrence treated with EBUS-FNA with a long-term follow-up

Bronchogenic cysts are congenital abnormalities generally mediastinal and are frequently detected incidentally. We report a case of a symptomatic mediastinal cyst treated previously by video-assisted thoracoscopy (VATS) but complicated by pericystic adhesions. The subsequent incomplete excision led, after 8 months, to a cyst's recurrence that was accurately drained by endobronchial ultrasonography-guided fine needle aspiration (EBUS-FNA), with no new regrowth after 18 months. We hypothesized that the support of a high-definition diagnostic tool (EBUS) improved the FNA ability to make a deep and complete aspiration of the cyst. The usefulness of FNA in bronchogenic cyst's treatment is underestimated. Our experience is an attempt to encourage the use of EBUS-FNA as a new therapeutic option in the management of bronchogenic cyst.
