Idiopathic Pulmonary Artery Aneurysm: A Case Report

Abstract

Background: Idiopathic pulmonary artery aneurysm is a rare disorder that has been reported in less than 50 cases. This complication is often asymptomatic, while the first manifestation can be severe hemoptysis or death. Case presentation: A 36-year-old man who presented to our institute with hemoptysis and fever. Dilated pulmonary artery trunk (5.5 cm) and the left pulmonary artery branch (6.90 cm) were discovered during a computed tomography angiogram scan in the patient's chest region. Therefore, the patient was diagnosed with a pulmonary artery aneurysm. According to the results of the tests requested for the patient, the cause of the patient's pulmonary artery aneurysm was not determined. Therefore, an idiopathic pulmonary artery aneurysm was proposed for the patient. Conclusion: Idiopathic pulmonary artery aneurysm poses a double diagnostic and therapeutic problem. The rarity of the disease, the absence of specific clinical signs make diagnosis difficult.

Pulmonary Artery Aneurysm: A Rarity and Surgical Enigma

“…In addition, PAAs due to infectious causes, such as syphilis, tuberculosis, and mucormycosis, have been described in reports [ 5 ]. Lastly, PAAs can be defined as idiopathic in the absence of any clear etiology [ 6 ]. The case presented here occurred in the setting of pulmonary hypertension, likely due to multifactorial causes of congenital heart disease and extensive cardiac history.…”

“…PA aneurysms may also occur secondary to pulmonary hypertension, autoimmune diseases or vasculitis. Finally, PA aneurysms with no clear cause were considered idiopathic[ 4 - 6 ]. Generally, PA aneurysms are less often clinically evident and are usually diagnosed based on chest radiographs or at autopsies[ 7 ].…”
