Unexpected diffuse lung lesions in a patient with pulmonary alveolar proteinosis: A case report

Figure 1 Chest computed tomography scan shows diffuse infectious lesions in both lungs with the possibility of opportunistic pneumonia, and it was recommended to combine these findings with the findings of the clinical and treatment follow-up. A: The right middle lobe, left lingula, and both lower lobes of the lungs exhibit diffuse ground-glass opacities; B: Both basal segments of the lower lobes of the lungs show diffuse ground-glass opacities.

Figure 2 Chest computed tomography scan shows scattered patchy ground-glass shadows in both lungs, which was consistent with alveolar protein deposition, with lower density than the October 23, 2022 film. A: The diffuse ground-glass opacities in the right middle lobe, left lingula, and both lower lobes of the lungs have significantly resolved compared to previous findings; B: The diffuse ground-glass opacities in both basal segments of the lower lobes of the lungs have significantly resolved compared to previous findings.
