Diagnosis With Brief Discussion

Diagnosis
Malignant mesothelioma
Radiologic Findings
Chest radiographs show fibronodular opacities in both upper and mid-lung zone with apical pleural thickening suggesting inactive tuberculosis, and 5 cm x 3 cm mass-like lesion in the left upper lung zone showing spiculated medial margin.

Chest CT scan reveals 5.6 x 2.6 cm mass based on pleura showing air-bronchogram in the left upper lobe. We had differentiated primary lung cancer as the first choice rather than mass originated from the pleura. The patient had been underwent thoracoscopic biopsy for left upper lateral pleural mass and excisional biopsy for palpable left supraclavicular lymph node. Pathologic diagnosis from pleural mass and lymph node was malignant mesothelioma. This patient has no past history of asbestos exposure. Lung parenchyma seemed to be infiltrated by the pleural lesion.
Brief Review
Malignant mesothelioma is the most common primary malignancy of the pleura. Asbestos exposure is found in about half of all patients with diffuse malignant mesothelioma. Development of pleural mesothelioma occurs up to 40 years following exposure to asbestos.

The peak age at presentation is between 40 and 70 years, with male predominating. Imaging findings are essentially similar on chest radiographs, CT, and MRI. Imaging findings typically consist of extensive nodular or lobular thickening of the pleura, which may conglomerate to form a circumferential lobular sheet of soft tissue density encasing the lungs.

The tumor often runs into the fissures accompanied by varying amount of pleural effusions. Invasion of chest wall, adjacent lung, pericardium, other mediastinal structures, and diaphragm usually occur relatively late.

Lymphatic and hematogenous metastases are usually late manifestations.

The differential diagnosis includes pleural involvement by other malignant tumors as well as benign conditions such as asbestos-related benign pleural effusion, asbestos-related pleural plaque, tuberculous pleural thickening, and empyema.
