Purpose:
Understanding the radiographic appearance and normal rate of fluid accumulation after pneumonectomy is important in order to detect postoperative complications.
Methods:
Upright posterior-anterior chest radiographs of 94 postpneumonectomy patients were assessed for the rate of pleural fluid accumulation as a percentage of hemithorax volume.
Results:
Overall median time to 70% hemithoracic opacification was 3 days and mean time was 27 days. The median time to 100% opacification was 66 days and mean time was 96 days.
Conclusion:
The median time to 70% hemithoracic opacification postpneumonectomy is 3 days, while median time to 100% opacification was 66 days.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
