The most frequent benign pleural disease is pleural effusion; other benign conditions involving the pleura include empyema, pneumothorax, pleural plaques, and fibrothorax. Malignant pleural disease is a common clinical problem, as about 25 % of all pleural effusions in elderly patients have a neoplastic origin. The pleura may be involved by one of several primary or secondary malignant tumors. Primary tumors account for about 10 % of pleural malignancies and are malignant pleural mesothelioma, localized fibrous tumor, and pleural sarcoma. Secondary tumors account for about 90 % of pleural neoplasms; the principal causes are adenocarcinoma or, less frequently, lymphoma and thymoma. Depending on the location, size, and underlying histologic features, pleural tumors may produce a spectrum of findings; CT is the best method for characterizing location and composition of pleural masses and is particularly useful in distinguishing pleural from peripheral pulmonary lesions. In this chapter, imaging features of the above-mentioned pathological entities are described.

Abstract
The most frequent benign pleural disease is pleural effusion; other benign conditions involving the pleura include empyema, pneumothorax, pleural plaques, and fibrothorax. Malignant pleural disease is a common clinical problem, as about 25 % of all pleural effusions in elderly patients have a neoplastic origin. The pleura may be involved by one of several primary or secondary malignant tumors. Primary tumors account for about 10 % of pleural malignancies and are malignant pleural mesothelioma, localized fibrous tumor, and pleural sarcoma. Secondary tumors account for about 90 % of pleural neoplasms; the principal causes are adenocarcinoma or, less frequently, lymphoma and thymoma. Depending on the location, size, and underlying histologic features, pleural tumors may produce a spectrum of findings; CT is the best method for characterizing location and composition of pleural masses and is particularly useful in distinguishing pleural from peripheral pulmonary lesions. In this chapter, imaging features of the above-mentioned pathological entities are described.
