Multiple pulmonary nodules: and if it was not a cancer.

A 72-year-old woman was admitted in the Cardiology Department for respiratory insufficiency. ECG revealed atrial fibrillation, and echocardiography revealed heart failure with an estimated left ventricular ejection fraction of 25%. Chest roentgenogram revealed multiple nodules, and chest CT scan revealed multiple dense nodules surrounded by ground-glass attenuation (halo sign) with unilateral pleural effusion (figure 1). A bronchoalveolar lavage was performed to rule out any infection. Anticoagulation was begun before a successful external cardioversion, followed by oral amiodarone treatment. Diuretics were increased without any other medication. One week later, a control chest CTscan revealed the disappearance of all nodules, as well as of the pleural effusion (figure 2).
