    Abstract:
    A 50-year-old female with a 20-year history of multifocal pulmonary benign metastasizing leiomyoma (BML), and asthma presented with subacute worsening of chronic dyspnea. A contrast-enhanced computerized tomography of the chest showed a single 1.4 × 1.5-cm contrast-enhancing mass in the right lower lobe among numerous non-enhancing bilateral pulmonary BML lesions. Pulmonary angiogram was not performed at that time due to clinical improvement. Four years later, the patient presented with refractory subacute worsening of her chronic dyspnea and was referred for embolization of the pulmonary arteriovenous malformation (PAVM). Two feeder arteries to the PAVM were embolized; each with a 6-mm Amplatzer-IV vascular plug and a 4-mm Nester coil. Follow-up angiograms demonstrated no flow through the PAVM. The patient's dyspnea resolved and she remained asymptomatic at one-year follow-up.
