Clinical evolution of antisynthetase syndrome-associated interstitial lung disease after COVID-19 in a man with Klinefelter syndrome: A case report

Figure 1 Lung computed tomography examination in admission. There were diffuse multiple patchy heightening shadows in both lungs, with a partial bronchial inflation sign. A: Both upper lungs in the lung window; B: Middle lobe and tongue lobe in the lung window; C: Both lower lungs in the lung window; D: Both upper lungs in the mediastinal window; E: Middle lobe and tongue lobe in the mediastinal window; F: Both lower lungs in the mediastinal window.

Figure 2 Lung computed tomography examination after methylprednisolone 40 mg paxlovid 6 d. Diffuse multiple patches of increased density in both upper lungs were significantly absorbed. A: Both upper lungs in the lung window; B: Middle lobe and tongue lobe in the lung window; C: Both lower lungs in the lung window.

Figure 3 Color ultrasound-guided percutaneous lung puncture. Organizing pneumonia with alveolar septal thickening was found under the microscope (hematoxylin-eosin). A: Original magnification × 10; B: Original magnification × 20; C: Original magnification × 40.

Figure 4 Lung computed tomography examination at 1 mo follow-up. Diffuse multiple consolidations in both lower lungs were significantly absorbed. A: Both upper lungs in the lung window; B: Middle lobe and tongue lobe in the lung window; C: Both lower lungs in the lung window.
