Abstract

Pleural effusions can develop as a result of over fifty different pleuropulmonary or systemic disorders of both benign and malignant etiologies. Consequently, the evaluation of patients with a pleural effusion is challenging since the differential diagnosis is broad. We present a case of a middle-aged woman with a left pleural effusion compatible with mononuclear predominant exudate and ADA level <40 units/L, her medical history includes being a heavy smoker with a history of breast cancer in complete remission, who underwent thoracentesis and pleural fluid analysis on three occasions, cytology being negative every time, she had a trapped lung, thoracoscopic biopsy with no evidence of malignancy, was finally diagnosed with bronchoscopy.
