“…Because the lumen is filled with mucus, mainly saliva, ultrasonographic images showed a homogeneous, hypoechoic image inside the lesion, with posterior echo enhancement (Figure 4). The typical ultrasonographic findings of a mucous cyst are a well‐defined border, anechoic internal echo, and absence of internal blood flow 2 . In our nine cases of mucous cysts, the border was unclear in three cases, and internal echogenicity was isoechoic in one case and hypoechoic in five cases.…”

The cases that differ from the typical images may be isoechoic or hypoechoic in intensity, probably due to fibrosis or scar formation in and around the lesion caused by repeated destruction and reformation from irritation, such as bites.…”

“…Another examination modality used to diagnose intraoral lesions or running blood vessels is intraoral ultrasonography. [1][2][3] This method uses an intraoral probe to directly scan the lesion. Several studies have described the use of intraoral ultrasonography, and the usefulness of intraoral ultrasonography for tongue cancer has been reported.…”

BackgroundMass lesions occurring under the oral mucosal epithelium are often small and difficult to diagnose; however, intraoral ultrasonography can delineate these lesions. We aimed to investigate the features of submucosal mass lesions in the oral cavity using intraoral ultrasonography.MethodsFifty patients with hemangioma, irritation fibroma, mucous cyst, lipoma, and pleomorphic adenoma were included. Age, site, largest diameter, thickness, marginal morphology type, border type, internal echo posterior echo, and internal or peripheral Doppler images of the lesions were recorded.ResultsThe hemangiomas were internally hypoechoic and exhibited a cord‐like structure; irritation fibromas, mainly internally isoechoic; mucous cysts, hypoechoic; and the lipomas appeared as homogeneous, isoechoic, or hyperechoic images with unclear borders. Pleomorphic adenomas were surrounded by a single hypoechoic zone, suggesting a thick capsular structure, were predominantly isoechoic internally, and appeared as cyst‐like hypoechoic images.ConclusionsThe features of the lesions were identified and delineated using intraoral ultrasonography.
