With no improvement in her symptoms, the computed tomography (CT) scan of the chest (Fig. 1A) revealed a left upper lobe consolidation. Half a month later, the range and density of the consolidation increased, and the left pleural effusion was newly seen (Fig. 1B). A CT scan of the chest (Fig. 1C) obtained 2 weeks after steroid treatment showed diminishment of the consolidations. At 6-month follow-up, the patient had no complaints of discomfort with no relapse of pulmonary lesions (Fig. 1D).
