Neutrophil predominance |
– Parapneumonic effusion – Pulmonary embolism – Early tuberculous pleuritis – Benign asbestos pleural effusion |
| Lymphocyte predominance |
– Malignancy – Tuberculous pleuritis – Lymphoma – Cardiac failure – After coronary bypass graft – Rheumatoid effusion – Chylothorax – Uremic pleuritis – Sarcoidosis – Yellow nail syndrome – Pulmonary embolism |
|
Eosinophilia (≥10% of nucleated cells) |
– Parapneumonic effusion – Drug-induced pleuritis – Benign asbestos pleural effusion – Eosinophilic granulomatosis with polyangiitis – Lymphoma – Pulmonary embolism – Parasitic infestation – Malignancy |
|
Pleural eosinophilia is a relatively nonspecific finding. | |
