In the case of air-fluid level
,air cysts and hydropneumothorax; hydatid cyst should be keep in mind(8).
or subdiaphragmatic air was not observed (Figure 1).
In some cases, intraparenchymal bronchogenic cysts may communicate with the bronchial tree, resulting in air-filled cysts or an air-fluid level
A plain radiograph (Waters view) revealed no signs of sinusitis, such as mucosal thickness or an air-fluid level
If the cysts are perforated, in lung graphy, some different findings can be encountered such as the image of lotus, meniscus sign, and air-fluid level
Multicentric bone destruction is an important finding to distinguish mucormycosis from a carcinomatous lesion arising from the mucosa of paranasal sinuses, and the absence of air-fluid level
distinguishes it from bacterial sinusitis.
The plain film findings of acute sinusitis include mucosal thickening, an air-fluid level
and partial or total sinus opacification of paranasal sinuses.
Sagittal contrast-enhanced T1-weighted image (C) show air-fluid level
in the cystic lesion suggestive of abscess cavity probably associated with air-forming bacterial infection.
The diagnosis of hydropneumopericardium requires the application of Shackelford criteria which include (i) high-pitched tympanic percussion note, (ii) loud metallic splashing sound synchronous with heart sounds, and (iii) characteristic chest X-ray with an air-fluid level
in the pericardial cavity.
Most patients with hiatal hernias are asymptomatic, and the diagnosis is made incidentally on chest x-ray as a retrocardiac air-fluid level
or on upper gastrointestinal studies.
Computed tomography (CT) and a barium swallow showed an air-fluid level
in a left-sided Zenker diverticulum (ZD) measuring 12 x 8.
A CT scan delineated a distended bladder with circumferential intramural air and intravesical air-fluid level
