[Other malignant tumors of the pleura].

Malignant tumors of the pleura are most often diffuse, nethertheless they are sometimes localized. There is an overlap of the radiologic features of the benign and malignant pleural lesions. The differential diagnosis may be difficult, even on histological sample. Imaging allows the diagnosis of pleural involvement, suggests the malignity, guides percutaneous or thoracoscopic biopsies of the pleura, defines extent of the tumor and follows the course of the disease. We will describe the malignant pleural tumors: pleural metastases, pleural involvement of broncho-pulmonary cancer, of lymphoma and leukaemia. Then the rare pleural tumors will be described: malignant pleural fibroma, sarcoma, histiocytoma and hemangiopericytoma.
