Transverse thin-section serial CT scans from a 55-year-old female with suspected COVID-19 pneumonia. Chest CT images performed on the 6th day after symptom onset indicated an enlarged mass with calcification in the left upper lobe and lung hilum and multiple mediastinal lymph node metastases (A1, B1, C1), bilateral diffused ground-glass opacities with partial consolidation (B2). Follow-up CT on the 15th day demonstrated continuous development in the scope and extent of lung lesions (C1, C2).
