Figure 1. Chest radiological findings upon admission and throughout the patient’s clinical course. Chest X-ray images taken in the supine position are depicted in panels (A) and (B). Panel (A) shows no evidence of pleural effusion on the day of admission, while panel (B) reveals bilateral pleural effusion observed on day 14 of hospitalization. Chest non-contrast axial computed tomography (CT) findings are presented in panels (C) and (D). Panel (C) displays severe left-sided pleural effusion and moderate right-sided pleural effusion on day 22 of admission, whereas panel (D) demonstrates a reduction in bilateral pleural effusion following treatment on day 65 of admission. Panel (E) showcases plain chest X-ray findings in the sitting position, revealing pleural thickening of the left lower lung and near disappearance of bilateral pleural effusions on day 79 of admission. The arrows indicate the lesions.
