Interstitial lung disease induced by the roots of Achyranthes japonica Nakai: Three case reports

Figure 1 Achyranthes japonicaNakai is called “Useul-ppuli. ”

Figure 2 Chest X-ray and computed tomography images of Case 1. A: At admission, chest radiography showed diffuse bilateral coalescent opacities; B: Contrast-enhanced chest computed tomography showed bilateral ground-glass opacities with interlobular interstitial thickening and patchy consolidation; C and D: After 4 mo, Chest radiography and high-resolution computed tomography showed almost improvement of ground-glass opacities, and patchy consolidation and peripheral reticulation were observed.

Figure 3 Chest X-ray and computed tomography images of Case 2. A and B: Baseline chest radiography and enhanced chest computed tomography at admission showed bilateral areas of ground-glass opacities and patchy consolidation; C: Follow-up high-resolution computed tomography on day 3 after systemic glucocorticoid therapy showed healing of the ground-glass opacities and consolidation; and D: Follow-up chest radiography on day 12 after systemic glucocorticoid therapy showed improvement of diffuse bilateral opacities.

Figure 4 Chest X-ray and computed tomography images of Case 3. A: At admission, chest radiography showed bilateral lung consolidation; B: Chest computed tomography showed diffuse and patchy areas of crazy-paving lesions and mixed consolidative lesions in both lungs; C and D: After 14 d of systemic glucocorticoid therapy, chest radiography and high-resolution computed tomography revealed resolution of ground-glass opacities with patchy consolidation.
