She reported a 3-month history of cough with whitish expectoration, and dyspnea on moderate exertion for the previous month and a half. She also complained of an episode of erythema, edema, heat and pain in the distal part of the left lower limb over the previous 15 days, which resolved without treatment.</p><p id="par0015" class="elsevierStylePara elsevierViewall">A bronchoscopy was performed in which no endobronchial abnormalities were observed.

In addition, magnetic resonance angiography cannot be performed in patients with metal implants, such as pacemakers.
