48 Possible Causes for Bilateral Hilar Adenopathy, Reticulonodular Pattern

  • Lymphocytic Interstitial Pneumonia

    Eight children of 12 had a reticulonodular pattern on chest radiographs. Two children had normal chest films and two children showed peribronchiolar thickening.[ncbi.nlm.nih.gov] It must be distinguished from pulmonary tuberculosis and bilateral hilar adenopathy (See Figure 6.2.D.4).[books.mcai.org.uk] Sarcoidosis stage I: left and right hilar and paratracheal adenopathy (1-2-3 sign) Stages Chest films in sarcoidosis have been classified into four stages: Bilateral hilar[radiologyassistant.nl]

  • Pulmonary Fungal Infection

    CXR findings include alveolar and mass-like infiltrates, though reticulonodular and miliary patterns can also be seen.[clinicaladvisor.com] . • Massive inhalation of organisms: – May show fairly discrete, nodular opacities 3-4 mm in diameter with hilar adenopathy 11.[slideshare.net] Fig. acute histoplasmosis widespread bilateral well-defined 3-5 mm nodules 12.[slideshare.net]

  • Pneumoconiosis

    […] or reticulonodular infiltrates.[scielo.br] Radiographs revealed multiple bilateral pulmonary nodules associated with hilar and mediastinal adenopathy.[ncbi.nlm.nih.gov] Occasionally, an obstructive pattern can be found. (4,6) The DLCO tends to decrease in the same proportion as TLC. (7,8) Chest X-rays can be normal or reveal mild nodular[scielo.br]

  • Coccidioidomycosis

    pattern (Figure 9).[appliedradiology.com] These infiltrates have been called "reticulonodular" because of their mixture of interstitial abnormalities and nodules.[doi.org] […] chronic coccidioidomycosis is less common than seen in association with tuberculosis or histoplasmosis. 16 Disseminated pulmonary infection can manifest as a miliary or reticulonodular[appliedradiology.com]
