Visualization obtained during medical thoracoscopy performed to evaluate a lymphocyte-predominant, exudative pleural effusion. The procedure was performed after two large-volume thoracenteses failed to yield a diagnosis. (A) Abnormal pleura studded with small parietal pleural lesions and hemorrhagic abnormalities at the costophrenic angle; (B) lung and visceral pleura adherent to parietal pleura, with another view of the abnormal parietal pleura studded with lesions; (C) hemorrhagic-appearing parietal pleura.
