Solitary Peripheral Pulmonary Artery Aneurysm Presenting as an Endobronchial Tumor: A Case Report
以支氣管內腫瘤表現的孤立性周邊肺動脈瘤：病例報告
並列摘要
Pulmonary artery aneurysms (PAAs) are rare. Hemoptysis is a common symptom of PAAs, but there are only a few case reports in the literature describing the bronchoscopic findings of PAAs. We report the case of an 18-year-old male with a solitary peripheral PAA, who presented with hemoptysis and an endobronchial tumor at the proximal left posterior basal segmental bronchus. Subsequent pulmonary artery angiography confirmed the diagnosis, and the patient was successfully treated with endovascular coil embolization. This case highlights the importance of including PAAs in the list of differential diagnoses of endobronchial tumors. Endobronchial ultrasound can provide more clues before invasive procedures are initiated. A biopsy should be avoided to prevent fatal hemorrhage.
