common and present a significant contribution to the workload of the chest radiologist. The radiology department plays a crucial role in the imaging and management of pleural disease. While a number of different imaging modalities may be used, chest radiography remains the first examination in the initial assessment of these patients. Depending on the clinical context, the optimal imaging technique for ­further evaluation may be computed tomography (CT), ultrasound (US) or magnetic resonance (MR). This chapter reviews chest radiograph findings for some pathologic pleural manifestations by correlating them with their
