Core Tip

Core Tip: Pulmonary artery (PA) aneurysms usually present as small or large lesions resembling inflammation or a neoplasm on chest radiography. It is rarely reported as an endobronchial mass. We report a case of a tumorous protrusion blocking the right middle lobe bronchus, which was confirmed to be a PA aneurysm by endobronchial ultrasound bronchoscopy and computed tomography angiography. Although endobronchial pulmonary arterial aneurysm is rare, bronchoscopists need to enhance their awareness and vigilance of this lesion in order to avoid the disastrous consequences caused by improper biopsy.
