Pulmonary artery aneurysm protruding into the bronchus as an endobronchial mass: A case report

Min Li et al. World J Clin Cases. .

Abstract

Background: Pulmonary artery (PA) aneurysms are usually diagnosed radiographically and present as small or large lesions resembling inflammation or a neoplasm on chest radiography. It has rarely been reported as an endobronchial mass.

Case summary: We report the case of a 64-year-old man who presented with recurrent hemoptysis. Bronchoscopy revealed a tumorous protrusion blocking the right middle lobe bronchus, which was confirmed to be a PA aneurysm using endobronchial ultrasound bronchoscopy and computed tomography angiography.

Conclusion: Although endobronchial PA aneurysms are rare, bronchoscopists need to add this lesion to the list of endobronchial masses for which a biopsy is to be assiduously avoided.

Keywords: Case report; Computed tomography angiography; Endobronchial mass; Endobronchial ultrasound bronchoscopy; Pulmonary artery aneurysm.
