Figure 2. A 56-year-old male patient presenting with myalgia: (A) His first axial unenhanced low dose chest CT showed GGOs with consolidation in the basal segments of the right lower lobe. Furthermore, there were multifocal and multisegmenter GGOs in the left lower lobe. Acute phase reactan levels were abnormal except for the first troponin on admission. CRP was 172 mg/L, procalcitonin was 3,8 ng/mL and D-dimer was 231 ng/mL; (B) After 4 days, the follow-up CT scan showed progression of the GGOs in the left lower lobe with a regression of the consolidation in the right lower lobe. Moreover, CRP was 41 mg/L, procalcitonin was 0.7 ng/mL, ferritin was 310 ng/mL, LDH was 297 U/L, D-dimer was 242 ng/mL.
