A chest X-ray and computed tomography (CT) showed an apical pulmonary cavity in the right lung with bronchiolitis and hilar lymphadenopathy (Figure 2(a)). Chest CT performed two months after stopping treatment showed regression of the lung cavity (Figure 2(b)).
(a) Bone scan showing increased radiotracer uptake (arrow) along the tubular bones of the upper and lower extremities consisting with periostosis. (b) The whole-body scan performed 14 months later showing the improvement of the scintigraphic abnormalities.
