Rare imaging findings of hypersensitivity pneumonitis: A case report

Figure 1 High-resolution computed tomography images. A: High-resolution computed tomography (HRCT) showed multiple nodules and ground-glass shadows in both lungs; B: Circular high density shadows of various sizes were widely distributed in both lungs with lung markings inside them; C: HRCT showed that the original nodules and ground-glass shadows were significantly absorbed at 1 mo, but a new nodule was found in the right upper lobe; D: Circular high density shadows were significantly absorbed at 1 mo; E: HRCT showed that the original nodules and ground-glass shadows were significantly absorbed; F: HRCT showed that the original circular high density shadows were significantly absorbed.
