C-protein 106.5 mg/L and erythrocyte sedimentation rate 71 mm/h). Chest X-ray exposed multiple nodular hypotransparent lesions scattered by both the lungs, and a CT scan showed parenchymal nodular areas with internal cavitation (Figures 1(a) and 1(b)). During outpatient follow-up, an angio-CT scan revealed complete resolution of pulmonary thromboembolism and nearly complete resolution of cavitated granulomas 4 months after onset of the disease (Figures 1(c) and 1(d)), and at this moment, clinical remission was achieved.
