Typically, an area of white lung is seen on a standard X-ray. [5] Consolidated tissue is more radio-opaque than normally aerated lung parenchyma, so that it is clearly demonstrable in radiography and on CT scans. Consolidation is often a middle-to-late stage feature/complication in pulmonary infections.
With pleural effusion, fluid often builds up in the costophrenic angle (due to gravity). This can push the lung upwards, resulting in "blunting" of the costophrenic angle. The posterior angle is the deepest. Obtuse angulation is sign of disease. Chest x-ray is the first test done to confirm an excess of pleural fluid.
First, many primary care providers perform a chest X-ray to look for a mass inside the lung. [8] The X-ray may reveal an obvious mass, the widening of the mediastinum (suggestive of spread to lymph nodes there), atelectasis (lung collapse), consolidation , or pleural effusion; [9] however, some lung tumors are not visible by X-ray. [5]
Malignant pleural effusion is a condition in which cancer causes an abnormal amount of fluid to collect between the thin layers of tissue lining the outside of the lung and the wall of the chest cavity. [1] Lung cancer and breast cancer account for about 50-65% of malignant pleural effusions.
A pleural effusion appears as an area of whiteness on a standard posteroanterior chest X-ray. [14] Normally, the space between the visceral pleura and the parietal pleura cannot be seen. A pleural effusion infiltrates the space between these layers. Because the pleural effusion has a density similar to water, it can be seen on radiographs.
A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by cancer. While this procedure usually generates only limited scar tissue, in rare cases a fibrothorax can develop.
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...
Laterolateral chest radiographs can increase the diagnostic accuracy of lung consolidation and pleural effusion. [ 41 ] A CT scan can give additional information in indeterminate cases [ 42 ] and provide more details in those with an unclear chest radiograph (for example occult pneumonia in chronic obstructive pulmonary disease).
