Abstract:

Objective: To analyze the special radiographic findings of chronic nephropathy pleural effusion, and improve the
knowledge of the characteristics of pathological pleural effusion. Methods: X-ray films from four patients with chronic nephropathy including nephrotic syndrome, renal failure, lupus nephritis and other, which were complicated with pleural effusion in different positions, were retrospectively analyzed. Results: Three cases showed effusion at right anterior of inferior mediastinum; 1 case showed right subpulmonic effusion and uncommon left posterior mediastinum effusion; 1 cases showed simple left subpulmonic effusion; and 2
cases showed right lobe of interstitial fluid accumulation, 2 cases showed small quantity of bilateral free fluid. Conclusion: There were some certain characteristics of chronic kidney disease complicated with pleural effusion, in addition to the free fluid and leaf interstitial fluid accumulation, the rare subpulmonic effusion, anterior inferior mediastinum effusion and more uncommon posterior mediastinal effusion should be taken into consideration.

Key words: chronic nephropathy, pleural effusion, subpulmonic effusion, anterior inferior mediastinum effusion, posterior
