There is water in the lungs, which means there is pleural effusion and hydrothorax. There are many reasons, such as increased hydrostatic pressure in the pleural capillaries, such as congestive heart failure, constrictive pericarditis, etc., and increased permeability of the pleura, such as inflammation, tuberculosis, pneumonia, rheumatic diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and pleural tumors, such as metastasis of malignant tumors, mesothelioma Inflammation under the diaphragm and so on can cause hydrops in the chest and lungs. Also, the decrease of colloid osmotic pressure in the capillaries of the pleura, such as hypoproteinemia, cirrhosis, nephrotic syndrome, acute glomerulonephritis, etc., will also produce hydronephrosis in the lungs. There are also mural pleural lymphatic drainage obstacles, injuries, iatrogenic factors, which can cause pulmonary hydrops. We need to go to the hospital for further screening to identify the cause.
