Most<unk>  are discovered as a chance finding on routine dental radiography. They are often asymptomatic unless there has been long-standing with significant enlargement (causing bony expansion or egg-shell cracking feeling) or secondary infection. On an x-ray,<unk>  appear as radiolucent (dark) areas with radiopaque (white) borders. However,<unk>  in maxillary sinus, also known as antrum, can appear radiopaque as the surrounding air absorbs fewer photons than the<unk> c fluid content.<unk>  are usually unilocular, but may also be multilocular. Sometimes aspiration (fine needle aspiration) is used to aid diagnosis of a<unk> c lesion; e.g., fluid aspirated from a radicular<unk> may appear straw-colored and display shimmering due to cholesterol content. Almost always, the<unk> lining is sent to a pathologist for histopathologic examination after it has been surgically removed. This means that the exact diagnosis of the type of<unk> is often made in retrospect, and definitive treatment can be made for the patient.
