Abstract

The diagnosis of malignant pleural mesothelioma relies mostly on the pathological examination of pleural samples, validated by a panel of experts and generally obtained during medical or surgical thoracoscopy performed for the management of an exudative pleural effusion. In the absence of pleural effusion (dry-type mesothelioma), the diagnostic approach depends on the features of the lesions (pleural thickness, nodules and/or masses) and their pleural location. Ultrasound and CT-guided needle aspiration represent recognized alternative diagnostic techniques in these situations. We present the case of a patient, presenting a dry-type mesothelioma, whose diagnosis was obtained by endobronchial ultrasound (EBUS)-guided needle aspiration of a pleural mediastinal mass and confirmed by a CT-guided needle aspiration of another pleural mass in close contact with the chest wall. The samples have been compared and show quantitative and qualitative similarities. EBUS represents a minimally invasive alternative diagnostic technique for dry-type mesothelioma, showing thickness of the mediastinal pleura in contact with a central airway or when thoracoscopy, which remains the “gold standard” diagnostic approach, is not feasible.
