Core Tip

Core Tip: We report a case of hypersensitivity pneumonitis (HP) with special high-resolution computed tomography (HRCT) findings. Circular high-density shadows of various sizes were widely distributed in both lungs with lung markings inside them. For some patients with HP, abnormal HRCT findings, such as the lesions in the lungs, can be absorbed on their own, which is an important clue in the diagnosis of the disease.
