A 48-year-old female was admitted to our department in June 2009, for stage II mMRC dyspnea associated to diffuse pulmonary opacities on chest X-ray (Fig. 1A). C). Calcifications were also present at the tracheobronchial tree (Fig. 1C and D). A bone scan was then performed, which showed bilateral and diffuse pulmonary hyperfixation (Fig. 1E).
