case_images: First lung CT scan, slight exudation, interstitial changes, and atelectasis in the upper lobe of the right lung, a medial segment of the medial lobe of the right lung, and the lower lobe of the right lung pointed by the red arrows (A). After 7 days of antibiotic treatment, multilocular encapsulating pleural effusion in the right upper and middle leaves pointed by the red arrows (B).

case_images: Bilateral local pleural thickening (Figure 1A). Therefore, cefazoxime sodium 2.0 iygtt q12h*7 days anti-infection therapy, while Lung contrast-enhanced CT also suggests a large encapsulated pleural effusion on the right side (Figure 1B), thoracentesis of the patient, can induce hemorrhagic turbid liquid, combined with carcinoembryonic antigen at 9.04ng/mL; CA125>1000.00U/ mL; CA15-367.2U/ mL; CA19-9>2000.00U/mL.
case_images: Right chest membranes were sent for examination. We used Hemalun eosin, hyperplastic cell nests were found in fibrotic adipose tissue (pointed by the red arrows, (A)), and specific hyperplastic cells were detected (pointed by the red arrows, (B)).
