Diagnostic Considerations

Consider the diagnosis of pulmonary arteriovenous malformations (PAVM) in individuals with any of the following presentations: (1) 1 or more pulmonary nodules associated with typical chest radiographic findings of pulmonary arteriovenous malformations; (2) mucocutaneous telangiectases; (3) unexpected findings such as dyspnea, hemoptysis, hypoxemia, polycythemia, clubbing, cyanosis, cerebral embolism, or brain abscess.
