Pulmonary artery pseudoaneurysm arising secondary to cavitary pneumonia.

Pulmonary artery pseudoaneurysms have classically been associated with the cavitary lesions of reactivation tuberculosis and termed Rasmussen’s aneurysm. There have been relatively few case reports of pulmonary artery pseudoaneuryms arising secondary to cavitary pneumonia. We present a case of pulmonary artery pseudoaneurysm occurring secondary to cavitating aspiration pneumonia that was treated successfully with coil embolization.
