His initial chest radiograph showed right upper lobe consolidation (Figure 1(a)). Follow-up chest radiograph two months later showed right upper lobe scarring and improvement in consolidation (Figure 1(b)).
(a) Chest axial view of CT performed on the day of admission, showing a thick-wall cavitary lesion (6.0 x 1.6 x 3.5 cm) in the right upper lobe of the lung. (b) Chest axial view of CT performed at 2-month follow-up, showing foci with ground glass opacity in the anterior right upper lobe of the lung surrounding a 9.9 mm nodular density. (c) Chest axial view of a CT performed at 3-month follow-up, showing complete resolution of the right upper lobe cavitary lesion.

Further evaluation by chest computed tomography (CT) showed a thick-walled, right upper lobe cavitary lesion (Figure 2(a)). Follow-up CT scan two months later showed foci with ground glass opacity in the anterior right upper lobe of the lung surrounding a 9.9 mm nodular density and three months later showed complete resolution of the cavitary lesion without sequelae (Figures 2(b) and 2(c)); the antibody titer for M. pneumoniae IgM was also reduced (1 : 160) 3 months later.
