case_images: CT scan images. (A) Chest CT showed an irregular mass at the right middle lobe of the lung near the interlobar fissure with right atelectasis and encapsulated effusion and pneumatosis. (B) Chest CT showed no significant changes in the amount of right-sided pleural effusion after thorough pleural drainage and anti-infective treatment for 3 weeks. (C) Contrast-enhanced CT scan showed uneven enhancement of the mass in the lateral segment of right middle lobe, mediastinal lymphadenopathy with visible enhancement, and a right hydropneumothorax on April 1. (D) Two weeks after readmission, chest CT showed that the right-sided pleural effusion and gas were significantly reduced.

case_images: Chest computed tomography (CT) revealed an irregular mass in the right middle lobe of the lung near the interlobar fissure with right atelectasis and thickening of the right pleura with encapsulated effusion and pneumatosis (Figure 1A). After repeated pleural effusion drainage and anti-infective treatment for 3 weeks, re-examination of lung CT showed no significant change in the amount of pleural effusion (Figure 1B). On April 1, a contrast-enhanced CT scan showed uneven enhancement of the mass in the lateral segment of the right middle lobe, mediastinal lymphadenopathy with visible enhancement, and a right hydropneumothorax (Figure 1C). Repeat chest CT revealed absorption of the fluid and gas in the right pleural cavity (Figure 1D).
case_images: The appearance of fiberoptic bronchoscopy and Pathological examination. (A) Complete stenosis of the airway in the lateral segment of the right middle lobe due to white endobronchial lesions. (B) A cauliflower-like mass was seen and biopsied. (C) Pathological examination of bronchial tissue in the middle lobe of the right lung shows a high-differentiated squamous cell carcinoma.

case_images: Fiberoptic bronchoscopy showed complete airway obstruction due to whitish endobronchial membranous lesions in the lateral segment of the right middle lobe (Figure 2A). A cauliflower-like mass was seen and biopsied after clamping the whitish endobronchial membranous lesions (Figure 2B). Histological examination of the biopsy specimens demonstrated a highly differentiated squamous cell carcinoma in the right lung (Figure 2C).
