Chest Radiograph
• Pleural Fluid as the Only Abnormality With Primary Disease in the Chest
• metastatic carcinoma • Wegener's ranulomatosis
• rheumatoid arthritis
from a nonlung primary • septic emboli
tumor.
• sarcoidosis
• tularemia

Value of Pleural Fluid Analysis
• the initial pleural fluid analysis is either definitively or presumptively diagnostic in 80% of patients and is valuable clinically in about 90% of cases.
• In a prospective study of 78 patients with new-onset pleural effusion,
• a definitive diagnosis was established by the initial pleural fluid analysis in 25% ,
• hemothorax (pleural fluid/blood hematocrit > 0.5)
• urinothorax (pleural fluid/serum creatinine > 1.0)
• peritoneal dialysis (total protein < 0.5 g/dl and glucose 200 to 400 mg/dL)
• nephrotic syndrome • chylous ascites
• urinothorax
• subphrenic abscess
• peritoneal dialysis • splenic abscess or infarction

4.Interstitial Lung Disease
• viral and mycoplasma pneumonias
• Waldenström's macroglobulinemia
• sarcoidosis • Pneumocystis carinii
pneumonia
7
5.Pulmonary Nodules
• most common causes • Less common causes
• a presumptive diagnosis in 55%, • with the remaining 20% having a
nondiagnostic pleural fluid analysis. (excluding possible diagnoses)
9
Value of Pleural Fluid Analysis
nail syndrome
lymphoma, and leukemia • uremic pleurisy
• pulmonary embolism
• constrictive pericarditis
• drug-induced lung disease
• hypothyroidism

2.Bilateral Effusions
• transudative effusions • congestive heart failure • nephrotic syndrome • hypoalbuminemia • peritoneal dialysis • constrictive pericarditis
• exudative effusions • malignancy
10
Diagnoses that can be definitively
• empyema (pus) • malignancy • tuberculous • fungal
• lupus pleuritis (lupus erythematosus cells)
• chylothorax (triglycerides > 110 mg/dL or presence of chylomicrons)
• Bilateral Effusions • Diseases Below the Diaphragm • Interstitial Lung Disease • Pulmonary Nodules
