“…Intrapulmonary aneurysms often present with massive or intermittent hemoptysis. Although mediastinal aneurysms may manifest as a mediastinal mass, acute superior vena cava obstruction, dysphagia, hemothorax, hemomediastinum, and hematemesis can occur 10. On imaging, hemothorax and hemomediastinum are the most common findings1; CT angiography is the primary noninvasive diagnostic modality for BAAs 11.…”

Nontraumatic spontaneous rupture of a bronchial artery aneurysm is rarely seen. In this report, we described such a phenomenon in a patient induced by usage of anticoagulant agent. The patient had no antecedent history of trauma, hypertension, or apparent aortic pathology. The patient who had been taking low-molecular-weight heparin and warfarin to treat deep vein thrombosis complained of a sudden upper abdomen pain with shortness of breath and hypoxemia. The patient was diagnosed and treated for an acute hemomediastinum caused by a ruptured bronchial artery aneurysm. If the patient had continued to take the anticoagulant antithrombotic drugs, it may cause a more virulent bleeding. Taken together, CT angiography is a useful diagnosis tool for patients with sudden chest pain and abdominal pain, and rare cause should be considered.

“…Not uncommonly, patients have a history of chronic inflammatory disease, ranging from arteritis to chronic bronchitis. This suggests that the etiology may be chronic inflammation surrounding, or directly involving, the artery [6,7]. In this case, the patient had a history of pulmonary tuberculosis 20 years earlier.…”

“…Intrapulmonary aneurysms often present with massive or intermittent hemoptysis. Although mediastinal aneurysms may manifest as a mediastinal mass, acute superior vena cava obstruction, dysphagia, hemothorax, hemomediastinum, and hematemesis can occur [6]. The primary diagnostic modes are computed tomographic angiography, intra-arterial angiography and, occasionally, magnetic resonance imaging in confusing cases [8].…”

Spontaneous Hemomediastinum and Hemothorax Caused by a Ruptured Bronchial Artery Aneurysm

A bronchial artery aneurysm (BAA) is uncommon and usually associated with chronic inflammatory lung disease or a systemic vascular condition, which is rarely the etiology of mediastinal hemorrhage. A middle-aged person presented with spontaneous hemothorax and hemomediastinum. A diagnostic evaluation identified a bronchial artery aneurysm as the source. To prevent further rupture, we performed a bronchial artery embolization. In the absence of trauma or other causes for hemothorax and mediastinal hemorrhage, the possibility of a BAA should be considered. A bronchial artery aneurysm can be managed by interventional techniques as well as surgery.

“…CT imaging is the diagnostic modality of choice. Because of increased use of cross-sectional imaging, mediastinal bronchial artery aneurysms are now being diagnosed not only in symptomatic patients, but also as incidental findings in the asymptomatic populace (2,4–7). …”
