Answer

Chest radiography findings are as follows [26, 27] :

  • Pulmonary opacities can be found in 26%-77% of cases of EGPA; films demonstrate no abnormalities in approximately 25% of patients [27]

  • Localized parenchymal opacities usually are bilateral, peripheral, and patchy.

  • Cavitation is rare.

  • Pulmonary infiltrates may be transient; occasionally, infiltrates are similar to those observed in patients with chronic eosinophilic pneumonia, or they may be nodular (see the image below).

  • Extensive air-space opacities in the setting of a drop in hemoglobin levels suggest massive intra-alveolar hemorrhage as a result of pulmonary alveolar capillaritis; hemoptysis is present in only 45%-66% of cases.

  • Pleural effusions are observed in 5%-30% of cases and can be eosinophilic.

  • Hilar nodal enlargement has occasionally been reported.
