Rheumatoid pleural effusion in the absence of arthritic disease

Rheumatoid pleural effusion is an unusual complication of rheumatoid disease that typically presents subsequent to other more common manifestations of rheumatoid illness. The case of a 72-year-old woman with a rheumatoid pleural effusion is discussed. The patient presented with dyspnea, but without any history of rheumatoid arthritis. The patient was treated by thoracentesis, followed by video-thoracoscopy and pulmonary decortication. Postoperatively, the patient's effusion partially reaccumulated. Steroid therapy resulted in prompt and permanent resolution of the effusion. The patient remains asymptomatic 1 year after her presentation. The biochemical, serologic, and cytologic characteristics of rheumatoid effusions are reviewed.
