Figure 14b. Ascariasis in a 35-year-old man with migratory infiltrates. (a) Chest radiograph shows areas of ground-glass increased opacity in the right lower and middle lobes. (b) High-resolution CT scan shows areas of ground-glass attenuation that correspond to the findings in a. The resolution of radiologic findings 1 week later demonstrated the transient nature of the disease. Larvae and eggs of A lumbricoides were found at bronchoalveolar lavage and in a fecal smear, respectively, during the acute stage.
