[Malignant Pleural Mesothelioma Presenting Refractory Pneumothorax Successfully Treated by Intrapleural Administration of Diluted Fibrin Glue;Report of a Case].

Malignant pleural mesothelioma sometimes accompanies intractable neumothorax due to the visceral pleural invasion of the tumor. A 68-years-old man was found to have massive pleural effusion and pleural mass combined with pneumothorax by computed tomography(CT). CT guided biopsy revealed the mass to be malignant pleural mesothelioma. Since continuous air leakage was observed by chest drainage, pleurodesis by OK-432 twice and bronchial occlusion by Endobronchial Watanabe Spigot (EWS)were performed. But air leakage continued, and the surgery was performed, however the treatment failed to stop the air leakage. Finally, the intrapleural administration of diluted fibrin glue was challenged and the air leakage stopped immediately after the treatment.
