Case of the Week: Sialolith with layers (CBCT)

Posted on by Dr. Shawneen Gonzalez

This week I have a case of a sialolith on CBCT (still images and videos) showing the layers of calcifications as it grows. First some information on sialoliths.

QUICK DEFINITION: Sialoliths are calcifications within the ducts of the salivary glands. Most commonly associated with the submandibular salivary gland in the submandibular (Wharton) duct. Patients may be asymptomatic or have swelling especially during eating.

RADIOGRAPHIC DESCRIPTION (LESION) – CBCT:

  • Location = floor of the mouth (best visualized on axial and coronal views).
  • Edge = well-defined.
  • Shape = round/ovoid.
  • Internal aspect = radiopaque, may have layers (laminated appearance – looks like the inside of an onion).
  • Other = N/A.
  • Number = typically single.
Note the radiopaque entity over the roots of the mandibular right second premolar and first molar.
Radiopaque mass in floor of the mouth on an axial view.
Radiopaque mass in the floor of the mouth on a coronal view.

Thanks and enjoy!
