Bronchial artery aneurysm presenting with epigastric pain that improves with vomiting

A 64‐year‐old man presented to the emergency department with a chief complaint of epigastric pain that improved with vomiting. He was initially treated for gastrointestinal disease, but computed tomography (CT) showed a mediastinal haematoma and contrast‐enhanced CT and bronchial arteriography showed a bronchial aneurysm. Bronchial artery aneurysm is a rare but potentially life‐threatening condition that can lead to haemorrhagic shock if it ruptures. Patients with bronchial aneurysms may present with symptoms similar to that of gastrointestinal diseases owing to increased pressure in the mediastinum caused by mediastinal haematoma.
