Caption: FIGURE 1: Computed tomography angiography of the thorax showing well-circumscribed, ovoid "cannonball" costophrenic
mass in right lower lung lobe, consistent with appearance of metastasis.
Caption: Figure 1: (a) Preoperative chest X-ray shows right sided obliteration of costophrenic
angle and displaced right lung.
Chest X ray (PA view) showing in-homogeneous opacities in right upper lope, linear fibrotic opacities in right middle lobe and blunting of right costophrenic
Repeated chest X-ray showed expanded lungs, but the left dome of the diaphragm was elevated and the costophrenic
angle was blunted with retained blood in the left thoracic cavity [Figure 4].
(3) As the disease progresses, the Langerhans cells recede from the end stage, fibrotic areas which then appear as hypocellular, stellate shaped scars and variable cysts in the pulmonary parenchyma that give rise to the radiologic features (Figure 1).2,3 CT demonstrates nodules, reticular changes and in advanced disease, peribronchiolar irregularly shaped cysts of variable sizes in upper and middle lobes with characteristic sparing of the costophrenic
The chest radiographs (with incomplete field of view due to technical processing damage) demonstrated important blunting of the costophrenic
sulci on the right.
A chest X-ray demonstrated occupation of the right costophrenic
Depending on the size of the effusion, these features can vary from blunting of the costophrenic
Pericardial cysts are rare benign structures, most frequently located in the right costophrenic
Thoracocentesis was performed and obtaining fluid (pleural effusions and frank empyema fluid identified by obliteration of costophrenic
angles on chest x-ray) from the pleural space was tested for gram stain and culture to isolate pneumonic infection by biochemical analysis.
To distinguish anterior peridiaphragmatic lymph nodes from pleural thickening along the costophrenic
sulci, multiplanar imaging was used.
