Learning objectives Review imaging findings of pleural diseases differential diagnosis.
Read more Background Pleura is a thin, two layered serous membrane that lines the lungs and thoracic cavity. Visceral pleura lines the lungs and invaginates to form the major and minor fissures, and the parietal pleura lines the chest wall, mediastinum, and diaphragmatic surface.[1]In general, when pleural disease is suspected, chest radiographic is the initial imaging study of choice, following by computed tomography (CT) if chest radiography findings raise suspicion. Ultrasound is frequently used to distinguish pleural thickening from effusion and to characterize,...
Read more Findings and procedure details There is a broad spectrum of pleura abnormalities, and ranges from: infections, systemic diseases, tumors or traumatic etiologies. [2]Those pathologies can manifest as a pleural effusion, pneumothorax, pleural thickening and pleural calcifications.[3]- Pleural effusions, the normal volume of fluid in each pleural space is aproximately 8 ml.[1] Pleural fluid  are classified based on their compositions: exudates ex: empyema that can complicate with a bronchopleural fistula; or transudates ex: cirrhosis.  Other specific causes of pleural effusion are chylothorax and hemothorax. [fig 1] [2] Parapneumonic effusions...
Read more Conclusion Knowledge of these features can differentiate among a broad spectrum of etiologies of pleural pathologies, narrowing the differential diagnosis and eventually suggesting a diagnosis or recommending further examinations.
