[A solitary, defined radiolucency on a panoramic radiograph; cyst or no cyst?]
Abstract:
Sharply defined radiolucencies on a panoramic radiograph are often interpreted as cystic laesions. In some cases, however, it appears to be another condition, or an anatomical variation. In the present case, involving 2 healthy patients, 1 or more sharply defined lucencies were seen in the lateral parts of the mandible. After exploration, in both cases, an empty cavity was found without epithelial lining, which is pathognomonic for a simple bone cyst. Multiple occurrences are uncommon.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
