case_images: Chest computed tomography (CT) displayed patchy infiltrates in the right upper lung with enlargement of hilus pulmonis and mediastinal lymph nodes (Figure 1A). Re-examination of chest CT indicated that the enlarged hilar lymph nodes had gradually shrank (Figure 1B-E), and the lung lesions were significantly absorbed (Figure 3A-C).
case_images: (A and B) pathological examination of H&E staining (H&E, 100x; H&E, 400x) from the cervical lymph nodes suggested granulomatous inflammation. Granulomas is composed of epithelioid cells in the lymph nodes. PAS(-).
