Confronting Upside-Down Video-Assisted Thoracic Surgery Approach for Hemorrhagic Bronchogenic Cyst Manifested by Sudden Back Pain.

Introduction: Bronchogenic cysts, arising from an aberrant bronchial primordium inclusion during the fetal period, are typically located in the mediastinum but can develop in ectopic regions. While generally asymptomatic, these cysts may become symptomatic due to infection or, rarely, hemorrhage. This report details a case of a hemorrhagic bronchogenic cyst in the supradiaphragmatic region, successfully resected using video-assisted thoracic surgery (VATS) with a confronting upside-down monitor setting.
