title: Mediastinal bronchial artery aneurysm with hematemesis.
abstract: Mediastinal bronchial artery aneurysm is a rare condition which can lead to potentially fatal hemorrhage. In most cases it presents respiratory symptoms due to rupture into pleural parenchyma. But when it develops mediodorsally and compresses the esophagus, it may cause dysphagia or hematemesis. Here we report a case of mediastinal bronchial artery aneurysm which presented with hematemesis. Computed tomography and endoscopic ultrasound showed what seemed to be a submucosal tumor on the esophagus. We were able to correctly diagnose the aneurysm using magnetic resonance imaging and probe thoracoscopy, and were able to successfully treat with transluminal artery embolization.
